                                 ABOUT CARESIDE

      This summary does not contain all of the information that you should
   consider before investing in our common stock. You should read the entire
   prospectus carefully, including the "Risk Factors" section, the financial
            statements and the notes to those financial statements.

        Careside has developed and sells a proprietary blood testing system
called the Careside system. It is designed to decentralize laboratory
operations. The system consists of two blood testing devices and disposable
cartridges and reagents used in the devices as well as a computer link. The
Careside Analyzer(R) tests each of the three components of blood - whole blood,
serum and plasma. It uses our proprietary disposable test cartridges and
performs 41 different tests. The H-2000 performs 18 hematology tests on whole
blood. The Careside Connect facilitates data interchange between the two devices
and other medical information systems.

        The Careside system performs blood tests in the same location as the
patient, or what is commonly called point-of-care testing. Blood testing is a
significant part of routine and critical patient care. Today, almost all blood
testing is done by sending the blood samples to hospital or commercial
laboratories. Because of transportation time and several processing steps, these
central laboratories generally take between 4 and 24 hours to provide test
results to the doctor. We believe the Careside system is a platform for solving
the limitations of central blood testing laboratories and redefines the market
for point-of-care testing. Our goal is to make decentralized testing with the
Careside system the standard for routine and critical care blood testing.

        As of August 2001, the FDA has cleared or exempted the Careside Analyzer
for all 41 blood tests for professional laboratory use and the H-2000 for 18
additional hematology tests. The Careside system's 59 different blood tests
represent most of the routine blood tests ordered by physicians. In addition,
the FDA has cleared the Careside Analyzer as a "point-of-care" device. This
clearance means that properly trained non-technical personnel can operate the
Careside Analyzer, eliminating the need for a lab specialist to oversee each
test. We intend to seek the same designation for the H-2000 in 2002.

        Our commercial product launch occurred in December 1999, at which time
the Careside system offered 53 tests. By the beginning of the second quarter of
2000, we were experiencing issues in both the software and hardware of the
Careside Analyzer that made us question the reliability of the device in the
field. We also experienced technical problems with electrochemistry tests. As a
result, we pulled back from the market and corrected the issues that gave rise
to the reliability concerns. We did not lose any customers or have to repurchase
any devices or have to seek any additional governmental approvals as a result of
these technical difficulties. Rather, we worked with our customers to ensure the
reliability of the test results each customer received from the Analyzer. We
completed the revisions to the electrochemistry tests and modifications to the
Analyzer by November 2000. The revisions were made and verified in the fourth
quarter of 2000. The changes delayed our ability to market the Analyzer and its
disposable cartridges. As a result, our sales through early 2001 were
predominantly H-2000s.

        At present, we sell the components of the Careside system separately in
the United States through our own sales force. We have distribution agreements
with third party distributors to supplement our sales force. We have entered
into several distribution agreements and expect to finalize others in 2001. To
date, our H-2000 sales have been weighted towards foreign markets and veterinary
use. We are focusing our 2001 and 2002 marketing efforts on the U.S. human
market.

        Our concept and technology originated with SmithKline Beecham Clinical
Laboratories, Inc. (SBCL). In 1993, SBCL conducted extensive surveys of the
point-of-care market. As a result, in 1994, SBCL started our predecessor
business to develop the technology we use today. In November 1996, we acquired
the assets and contracts used in the predecessor business, including
intellectual property, equipment and other assets to continue the development of
point-of-care diagnostic technology and to create a commercial product. Several
senior members of our management team worked on this point-of-care project at
SBCL, including W. Vickery Stoughton, our Chief Executive Officer, and Thomas H.
Grove, Executive Vice President--Chief Technology Officer. Quest Diagnostics
Incorporated later acquired SBCL.

                                  RISK FACTORS

          An investment in our common stock involves many risks. These risks may
be substantial and are inherent in the business of Careside. You should
carefully consider the following information about these risks, together with
the other information in this prospectus, before buying common stock.

          If any of the following risks actually occurs, our business and
prospects could be materially adversely affected, the trading price of our
common stock or warrants could decline, and you might lose all or part of your
investment.

We Have A Limited Operating History By Which To Evaluate Our Business

          We have no history which would demonstrate an ability to generate
revenue. Since our inception, we have incurred significant losses. Through
December 31, 2000 and June 30, 2001 our accumulated losses have totaled $45.2
million and $52.2 million, respectively. We have generated only a small amount
of revenue from product sales and will continue to incur significant additional
operating losses until we have sold a sufficient number of our products. Because
we have a limited operating history, we have not demonstrated an ability to:

          .    respond to competitive developments;
          .    develop new relationships and maintain existing relationships
               with suppliers, distributors and potential customers;
          .    attract, retain and motivate qualified employees; and
          .    produce, distribute and market our product.

We May Never Be Profitable

          Even if we are able to generate revenue from sales of our products, we
may never be profitable. There are several reasons why this might happen:

          .    We may not be able to reduce our manufacturing costs to levels
               necessary for profitability.
          .    We may have to lower our prices to remain competitive.
          .    We may experience delays in developing additional tests or
               product upgrades.
          .    We may experience problems in production, distribution or
               marketing.

          Even if we do achieve profitability, we may not sustain or increase
profitability on a quarterly or annual basis in the future.

Given Our Limited Operating History And Recurring Losses, We May Be Unable To
Continue As A Going Concern.

Since our inception, we have generated minimal revenues, incurred significant
losses from operations and accumulated some debt. We anticipate that we will
incur additional losses over at least the next year. Our consolidated financial
statements for each of the three years in the period ended December 31, 2000
have been prepared assuming that we will continue as a going concern. As
indicated in our consolidated financial statements for the year ended December
31, 2000, we incurred a net loss for 2000 of $16,703,485 and used cash for
operating activities of $15,661,957. Our accumulated deficit was $45,199,361.
Careside's independent accountants have stated in their audit opinion that these
factors raise substantial doubt about Careside's ability to continue as a going
concern. Further, additional financing will be needed by Careside to fund its
operations. If we seek additional debt or equity financing in the future, these
factors, including the going-concern language in our independent accountant's
audit opinion, might hinder our ability to do so. In the event our operations
are not profitable or do not generate sufficient cash to fund our business,
there will be substantial doubt about our ability to continue as a going
concern.

                                       -5-



Unavailability Of Additional Funding May Adversely Affect Our Business

          At June 30, 2001, our principal source of liquidity was approximately
$5.6 million in cash and cash equivalents. Our current liquidity and sales
revenue expected in 2001 are projected to be sufficient to fund our operating
expenses and capital requirements for at least two months. However, certain
uncertainties may impact our ability to fund our planned operations and to meet
our operating objectives. Our future liquidity and capital funding requirements
will depend on numerous factors, including:

          .    the extent to which our products gain market acceptance;
          .    the exercise of outstanding warrants to purchase common stock;
          .    the timing of regulatory actions regarding our products; and
          .    the costs and timing of expansions of sales, marketing and
               manufacturing activities.

Additional capital may not be available on terms acceptable to us, if it is
available at all. If adequate funds are not available, our business, results of
operations and financial condition could be materially and adversely affected.
We may be required to delay, reduce or eliminate product development programs or
to sell our business. We may also have to reduce our planned marketing and sales
activities, or license to third parties rights to commercialize our products or
technologies. These reductions could, in turn, affect our relationships with our
clients and threaten our ability to continue as a going concern.

The Medical Community May Not Accept the Careside System

          The Careside Analyzer and our patented test cartridges, the H-2000 and
the Careside Connect are our only products. We will not be able to operate
profitably unless these products achieve a significant level of market
acceptance. The following factors are the greatest risks to our market
acceptance:

We May Fail to Develop the Comprehensive Test Menu Needed to Sell Our Product

          If we are not able to fully develop further tests to complete our
proposed comprehensive test menu, customers may not buy our products. One of our
major selling points to potential customers will be the breadth of our menu.

   We May Be Unable to Change How Tests Are Ordered

          We may not be able to demonstrate the economic or clinical benefits of
the Careside system sufficiently to convince members of the medical community to
change the way they order tests. Currently, physicians and hospitals typically
order blood tests from central laboratories.

   Managed Care Contracts May Limit Our Market Penetration

          Our ability to sell to healthcare providers may be limited by managed
care relationships. Many health maintenance and managed care organizations have
exclusive contracts with laboratories that require participating or employed
physicians to send patient specimens only to contracted laboratories.
Consequently, these physicians may be precluded from using Careside's products
unless they obtain a waiver from the relevant health maintenance or managed care
organization.

   We May Be Unable to Keep Pace With Changing Technology

          Blood testing technology is evolving. Other companies may develop
products in response to technological changes that make our products
noncompetitive.

                                       -6-



   CLIA May Discourage Healthcare Providers from Using Point-of-Care Testing

          Careside system users will have to be licensed under the Clinical
Laboratory Improvement Amendments of 1988. While the Careside system is designed
to make licensure easy, CLIA licensing requirements may make healthcare
providers reluctant to initiate, continue or expand patient testing using the
Careside system.

We May Not Be Able to Further Develop Our Products

          In order for us to expand our test menu, we must complete the
development of one of the four types of disposable cartridges. The
immunochemistry cartridge has been designed but has not undergone testing.
Factors outside our control may delay our proposed development schedule for this
cartridge. These factors include:

          .    delays in regulatory clearance
          .    technological difficulties
          .    restrictions on access to proprietary technology of strategic
               partners, and
          .    changes in the healthcare, regulatory or reimbursement
               environment.

Reductions in Third-Party Reimbursement for Tests May Hurt Our Business

          We believe that decreases in third-party reimbursement amounts for
diagnostic tests may reduce the demand for diagnostic tests performed by our
products at the point of care. Government authorities, private health insurers
and other third-party payers, such as health maintenance organizations, have the
power to determine reimbursement amounts paid to test providers for diagnostic
tests. Historically, they have decreased these reimbursement amounts more often
than they have increased them. While we have no knowledge of any upcoming
decreases, the potential for them exists. Providers would earn less revenue from
testing if reimbursement rates decrease. Because it may not be profitable enough
in light of reimbursement rates, providers could choose to cease or not to start
conducting point-of-care testing. This could, in turn, decrease the demand for
our products or force us to lower our sales prices. This could lower our
revenues.

Our Limited Sales, Marketing and Distribution Experience May Hurt Our Sales

          We may not be able to recruit or retain direct sales and marketing
personnel who will successfully implement our marketing strategy. We intend to
distribute our products in the United States through our own sales force and
domestic distributors, and internationally through distributors. Establishing a
sales and marketing capability will require substantial efforts and significant
resources.

Ineffectiveness of Third-Party Distributors May Hurt Our Sales

         We will depend on third party distributors to assist us in promoting
market acceptance and creating demand for our products. We have granted Fuji
Photo Film Co. Ltd. a right of first refusal to distribute the Careside system
exclusively in Japan and non-exclusively in some of the other Asian countries.
Our existing arrangements to distribute our products worldwide may not be
sufficient. We may not be able to maintain these arrangements or enter into
additional distribution arrangements. In addition, we have little control over
the resources that distributors will devote to the marketing of our products.

Our Contract Manufacturers May Not Adequately Meet Our Future Product Demand

          We will depend upon outside vendors to manufacture most of the
Careside system, including the Careside Analyzer and components of the
disposable testing cartridges. We have only limited control over third-party
manufacturers as to quality control and timing of production and delivery. We
cannot be certain that outside manufacturers will be able to provide us with a
sufficient number of instruments and cartridge components on a timely basis.

          At present, we depend on UMM Electronics, Inc. for the manufacture and
supply of Analyzers and Fuji Photo Film Co., Ltd. for dry film used in our
cartridges. Each of those suppliers has contracted to supply to us all of

                                       -7-



the products we order from them. If we do not negotiate extensions, our contract
with UMM will expire in the first quarter of 2004 and our contract with Fuji
will expire on December 31, 2003. There are alternative suppliers to UMM and
Fuji. However, if we are required to switch manufacturers or suppliers on short
notice, the manufacture of our products could be delayed and the supply of our
products could be interrupted. This could reduce our revenues.

Our Inability To Forecast Our Dry Film Requirements Could Result in Excess Film
Inventory

          Our contract with Fuji requires us to forecast our requirements for
dry film on a periodic basis. If we do not accurately forecast our needs, we may
end up with too much or too little supply of dry film. Excess film inventory
could result in obsolescence since dry film has a limited shelf life. Too little
inventory could hurt our ability to meet our customers' orders.

Our Lack Of Manufacturing Experience Could Prevent Us From Meeting Cartridge
Demand

          We will be assembling the cartridges at Careside. We limited
experience operating manufacturing/assembly business. We will need to assemble
significant and increasing quantities of test cartridges on a timely basis,
while maintaining strict quality standards. We have converted from manual
production of cartridge components and assembly to an automated system to
produce cartridge components. We may not be able to achieve and maintain product
accuracy and reliability when producing the cartridges in the quantities
required, on a timely basis or at an acceptable cost.

Loss Of Our CEO or Other Key Personnel Would Hinder The Success Of Our Business

          The loss of key employees or unsuccessful recruiting efforts will harm
us. Competition for qualified and talented individuals with experience in
point-of-care testing is intense. Our success depends on our ability to retain
the services of Mr. Stoughton, our Chairman of the Board of Directors and Chief
Executive Officer. Mr. Stoughton has over 20 years experience as a senior
executive of several large hospitals and over four years experience as President
of SmithKline Beecham Clinical Laboratories, Inc. We also need to attract
additional sales and marketing, research and development, and experienced
manufacturing personnel.

Failure To Manage The Expansion Of Our Operations May Hurt Our Business

          We will need to expand our operations if we are successful in
achieving market acceptance for the Careside system. This expansion will result
in additional responsibilities for management and place significant demand upon
our management, our operating and financial systems and our resources. To
accommodate this growth and to compete effectively, we will need to implement
and improve our internal operating systems and controls, and to hire and train
additional personnel. Failure to do so may impede our success.

Our Competitors Have Advantages Over Us

          Our business may fail because our market is highly competitive. Our
primary competitors are large diagnostic device manufacturers, commercial and
hospital laboratories and other point-of-care device manufacturers. The large
device manufacturers and commercial and hospital laboratories have significant
marketing, manufacturing, financial and managerial resources, and have
substantially greater research and development capabilities than we do. We
expect that manufacturers of conventional blood testing products used in
centralized laboratories will compete intensely with us to maintain their market
share. Commercial and hospital laboratories may try to influence providers
against the Careside system to protect their revenue. Other point-of-care
companies have already sold their product in the marketplace. We anticipate
competition from these manufacturers in discrete testing areas such as critical
care testing. Many of these companies offer tests that will cost less than the
Careside system and so may be attractive to some of our customers.

                                       -8-



Failure To Protect Our Proprietary Technology May Hurt Our Business

          The success of our business will depend on our ability to protect our
proprietary technology. Our business may fail if we are not able to do so.

         We currently have four U.S. patents granted on our cartridge
technology, one U.S. design patent covering the Careside Analyzer and one patent
held jointly with International Technidyne Inc. that covers a coagulation
reagent that was co-discovered . As we develop new technology, we may file
additional patents in the future. International patent appications have also
been filed. We cannot be certain that international patent applications will be
granted or that our patents will withstand any challenges by third parties.
Factors impacting our proprietary technology, which may ultimately impact our
success, include:

   Our Technology May Infringe on the Proprietary Rights of Third Parties

          Universities and government laboratories, physicians and other
corporations are conducting substantial research in point-of-care diagnostic
blood testing technology. Given the nature of our industry, it is possible that
patent applications have been filed by others, and patents may be issued to
them, relating to specific diagnostic products and processes. Patent
applications in the U.S. are secret until the patent is issued. We cannot know
whether competing applications have been filed. A prior conflicting patent
application would detract from the value of our patents. In addition, if we use
technologies, products or processes covered by patent applications filed by
others, or by patents issued to others, we may have to obtain licenses. We may
not be able to obtain such licenses on reasonable terms, or at all.

   We May Be Unable to Build Brand Loyalty Because Our Trademarks and Trade
   Names May Not Be Protected

          Our registered or unregistered trademarks or trade names may be
challenged, canceled, infringed, circumvented or declared generic or determined
to be infringing on other marks. We may not be able to protect our rights to
these trademarks and trade names, which we need to build brand loyalty. Brand
recognition is critical to our short term and long term marketing strategies.

   Our Trade Secrets May Be Disclosed

          We also rely on unpatented trade secrets to protect our proprietary
technology. We attempt to protect our proprietary technology through an employee
handbook and agreements with our executive officers. Our employees have not
signed confidentiality agreements. The confidentiality provisions in the
handbook and executives' agreements may not be enforceable under applicable law.
Other companies may independently develop or otherwise acquire equivalent
technology or gain access to our proprietary technology.

   Our Proprietary Rights May Fail to Protect Our Business

          We may have to resort to litigation to protect or defend our rights.
This could result in substantial costs and the diversion of management's
attention. If we lost any such litigation, we could lose our competitive
position, be required to obtain licenses from third parties or be prevented from
manufacturing, selling or using certain of our products.

   We Do Not Own All Necessary Intellectual Property

          The film in all of our test cartridges and the electrochemistry slide
in our electrochemistry test cartridge is manufactured by and is based on
patents owned by Fuji Photo Film Co., Ltd. Fuji may terminate its contract with
us upon one year's notice if it discontinues manufacturing and marketing this
film. It also may terminate the contract if we become bankrupt or insolvent or
if we transfer significant assets to a third party, if there is a material
change in control of us, or if we breach the agreement and the breach is not
cured within thirty days. If our access to these Fuji products terminated, we
would have to use other products that would be based on alternative technology.
We would not be able to utilize Fuji's patents to manufacture our own film and
electrochemistry slide because we do not have a perpetual license to Fuji's
patents if Fuji terminates its contract with us. We believe that such other
products do

                                       -9-



exist, but we cannot be sure that we would be able to achieve access to any such
technology on a timely basis. Conversion to the alternative technology could not
start until we achieve access to the alternative technology. If we have to use
products based on alternative technology, we may have to modify our product to
accommodate this new technology. This could cause substantial delay and cost. If
alternative technology is unavailable, we would have to change our testing
methodologies. This could also cause substantial delay and cost. We presently
have no indication that our access to the Fuji products is threatened and we
believe that there is only a small risk that we would be denied access to
alternative technologies.

Extensive Government Regulation May Increase Our Expenses and Cause Delays In
Our Product Commercialization

          Our products are medical devices subject to extensive regulation by
the FDA, similar agencies in other countries, and to a lesser extent, by state
regulatory authorities. The following are the greatest regulatory risks we face:

  We May Incur Substantial Expenses to Comply With Good Manufacturing Practices
  (GMP) and Other Manufacturing Regulations

          Our manufacturing facilities and processes will be required to comply
with strict federal regulations, including Good Manufacturing Practices, or GMP,
and quality system requirements, regarding validation and quality of
manufacturing. We have limited experience in complying with regulations
governing our products and manufacturing facilities. We must devote substantial
resources and management attention to monitoring and maintaining compliance with
governmental regulations. If we, or our manufacturing partners, violate
applicable regulations, we may be sanctioned and our production or distribution
may be suspended. In addition, the FDA may withdraw the approval or clearance to
market of any of our products.

  We May Need to Apply for Additional FDA Pre-Market Clearances if We
  Significantly Modify Our Products or Add to Our Test Menu, Which May Result
  in Rejections or Delays

          We are continuously subject to FDA regulations regarding laboratory
and clinical testing. When we seek to improve our product and add additional
tests to our test menu, we may be required to submit new applications for
pre-market clearance. We cannot be certain that we will be able to obtain all
necessary approvals for product improvements or additional tests on a timely
basis, or at all. Such delays or rejections could adversely affect our business.

                                      -10-



The Issuance Of Significant Number Of Shares That Are Eligible For Future Sale
Could Lower Our Market Price

     We have a significant amount of common stock that could enter the public
market in the future. The public resale of these shares could have a depressive
effect on the market price of our common stock.

     The following are the shares that may be issued in the future:

     .    2,000,000 common shares issuable upon exercise of our outstanding
          public warrants will become available for resale in the public market
          upon issuance;

     .    1,461,779 common shares issuable upon exercise of our outstanding
          options or options that we may grant in the future under our current
          stock option plans, or pursuant to our employee stock purchase plan,
          will become available for resale in the public market upon issuance;
          and

     .    11,471,788 common shares issuable upon exercise of outstanding
          warrants that are not publicly traded will become available for resale
          in the public market upon issuance

A Large Percentage Increase In Our Publicly Traded Common Stock May Lower The
Market Price of Our Common Stock

     Since our initial public offering on June 16, 1999, we have issued common
stock and committed to issue common stock through warrants and options which we
have issued and through our Series A preferred stock which we may become
obligated to issue in the future. On a fully diluted basis, we have increased
our outstanding common stock since our initial public offering by 163%.

     In this prospectus, we have registered the resale of 7,115,920 of our total
outstanding shares of common stock, which represents 42.1% of the number of our
publicly tradable shares after this registration. Also, we have outstanding
options and warrants that are exercisable into approximately 14,498,488 shares
of common stock, some of which are registered in this registration statement and
some of which have been previously registered. The issuance of these shares
would result in a 85.9% increase in our outstanding common stock. The large
percentage increases in our outstanding and registered common stock could have a
depressive effect on the market price of our common stock.

Holders Of Our Common Stock May Be Materially Diluted By The Exercise Of
Outstanding Warrants Issued in Connection With Our Series B and Series C
Preferred Stock

     3,993,970 additional shares of our common stock may be issued upon the
exercise of the callable common warrant issued in 2000 to the purchaser of our
series B preferred stock. The exercise price of this warrant can be 95% of a two
day average market price of our common stock. The issuance of these warrant
shares at such price may have a depressive effect of the market price of our
common stock.

     5,691,087 shares of our common stock may be issued upon the exercise of
warrants issued in 2001 in connection with the sale of our series C preferred
stock. The exercise price of these warrants is $2.55 for 5,173,716 of these
shares and $1.94 for the remaining 517,371 shares. Issuance of these shares at
an exercise price that is less than the market price of our common stock at that
time, may have a depressive effect of the market price of our common stock.

Control Of Careside By Our Management And Principal Stockholders Could Conflict
With Other Stockholders' Interests

     The interests of our directors and executive officers, and our principal
stockholders could conflict with the interests of other Careside stockholders.
As of the date of this prospectus, our directors and executive officers,
together with the principal stockholders of Careside, beneficially own or
control approximately 49.4% of our common stock. This percentage takes into
account the effect of options and warrants. Accordingly, these stockholders may
be able to influence the outcome of stockholder votes, including votes
concerning the election of directors, certain amendments to our charter and
bylaws, and the approval of significant corporate transactions such

                                      -11-



as a merger or a sale of our assets. This influence could have the effect of
delaying, deferring or preventing a change in control of Careside.

Future Issuances Of Preferred Stock May Dilute Rights Of Common Stockholders

     Because of our liquidity needs, we have issued in the past three different
series of preferred stock. Each such series of preferred stock has had superior
rights to our common stock. The conversion of each series of preferred stock
into our common stock may have caused or may in the future cause dilution to our
stockholders. Currently, no shares of preferred stock are outstanding. We are
obligated to issue shares of series A preferred stock if the remaining $2
million of our bridge financing with S.R. One, Ltd. originally entered into in
December 1998 is converted. Given our liquidity position, we may have to seek
additional capital in the future as we have done in the past. Our Board of
Directors has the authority to issue up to 4,836,117 additional shares of
preferred stock in the future and to determine the price, privileges and other
terms of such shares. The Board may exercise this authority without the approval
of the stockholders. The rights of the holders of common stock may be adversely
affected by the rights of the holders of any preferred stock that may be issued
in the future. Specifically, our series A preferred stock is preferred over
common stock in dividends and has a liquidation preference over common stock. In
addition, the issuance of preferred stock may make it more difficult for a third
party to acquire control of Careside.

Delaware Law, Charter And Our By-laws May Delay Or Prevent Someone From
Acquiring Us

     We will be subject to the anti-takeover provisions of Section 203 of the
Delaware General Corporation Law. Section 203 could delay or prevent a third
party or a significant stockholder from acquiring control of us. In general,
Section 203 prohibits a publicly held Delaware corporation from engaging in a
business combination with an interested stockholder for a period of three years
following the date the person became an interested stockholder, unless the
business combination or the transaction in which the person became an interested
stockholder is approved in a prescribed manner. Generally, a business
combination includes a merger, asset or stock sale, or other transaction
resulting in a financial benefit to the interested stockholder. An interested
stockholder is a person who, together with affiliates and associates, owns 15%
or more of a corporation's voting stock. Section 203 may prohibit or delay
mergers or other takeover or change in control attempts with respect to us. As a
result, Section 203 may discourage attempts to acquire us even though such
transaction may offer our stockholders the opportunity to sell their stock at a
price above the prevailing market price.

     In addition, our charter and by-laws contain anti-takeover protections that
may have the effect of lowering the market price of our stock because they may
discourage, delay or prevent a merger, tender offer or proxy contest involving
us. Specifically, our charter and bylaws contain the following anti-takeover
protections:

     .    the fact that we have a board of directors that it is divided into
          three classes of directors may have the effect of deterring or
          delaying any attempt by any group to obtain control of us by a proxy
          contest. A stockholder would be required to have its nominees elected
          at two separate annual meetings in order to elect a majority of the
          members of the board of directors;

     .    we may issue up to 4,836,117 shares of preferred stock that has
          whatever rights, privileges and preferences our Board of Directors
          determines. The issuance of preferred stock could be utilized as a
          method of discouraging, delaying or preventing a change in control of
          our stock;

     .    our charter requires that stockholder action be taken at meetings and
          not by written consent and that special meetings of stockholders may
          only be called by a majority of our board of directors, our chairman
          or our chief executive officer;

     .    our charter provides that directors can be removes from the Board only
          for cause and only with the affirmative vote of holders of 80% or more
          of our outstanding voting shares

     .    our charter requires a holders of 75%, and in some cases 80%, of our
          outstanding shares to approve any amendment to our charter;

                                      -12-



          .    stockholders must follow the advance notice procedures set forth
               in our bylaws to nominate a person for director or submit
               proposals to our Board of Directors; and

          .    our Board of Directors has broad discretion under our bylaws to
               determine the number of directors that will constitute our Board
               and to fill vacancies on the Board, including those created by
               increasing the number of directors.

The Market Prices Of Shares Of Common Stock And Warrants May Be Volatile

     The market prices of shares of common stock and warrants may be highly
volatile. This means our stock prices may fluctuate significantly depending on
many factors, including:

     .    the success of our new products or new products introduced by our
          competitors,

     .    developments with respect to our patents and other proprietary rights,

     .    our ability to meet sales and earnings expectations of securities
          analysts,

     .    our need to raise financing through the sale of our equity, and

     .    changes in general market conditions.

Our Total Assets Include Significant Intangible Assets And The Write-Off Of A
Significant Portion Of Unamortized Intangible Assets Would Negatively Affect Our
Results Of Operations

     Our total assets reflect significant intangible assets. As of June 30,
2001, we had approximately $1.9 million of net intangible assets representing
12.6% of our total assets and 21.2% of our stockholders' equity. Intangible
assets consist of goodwill associated with our acquisition of Texas Instrument
Laboratories, Inc., representing the excess of the purchase price and related
costs over the value assigned to the tangible assets we acquired in that
acquisition. Periodically, we assess whether there has been an impairment in the
value of our goodwill. Beginning January 1, 2002, we will account for our
intangible assets under Statement of Financial Accounting Standards No. 142,
Goodwill and Other Intangible Assets. Under this standard we will no longer
amortize our goodwill, but we will continue to periodically assess it for
impairment by comparing the carrying value to the estimated fair value. If the
estimated fair value is less than the carrying value, the goodwill will be
considered impaired and the impairment losses will be reported as an operating
expense in current results of operations. Any determination requiring the
write-off of a significant portion of unamortized intangible assets would
negatively affect our results of operations and total capitalization. As of June
30 2001, we have determined that no impairment existed.

The Terms Of Some Of Our Securities May Encourage Short-Selling Of Our Common
Stock Which Could Depress The Market Price Of Our Common Stock

     Until the warrants issued in 2000 in connection with our series B
convertible preferred stock are exercised, there may be increased risk of
short-selling of our common stock, which could have a depressive effect on the
market price of our common stock. The holder of this warrant can exercise on its
own initiative at $14 per share. Or, we can call this warrant in which case the
exercise price is 95% of the two day average trading price prior to the call. If
we call the warrant, then, by short-selling our common stock, the warrant holder
could depress the market price of our common stock, enabling the holder to
acquire shares upon any subsequent call of these warrants at a lower price.

     A short-sale is the sale of a security that the seller does not own or that
the seller owns but does not deliver. In order to deliver the security to the
purchaser, the short-seller will borrow the security, typically from a
broker-dealer or an institutional investor. The short-seller later closes out
the position by returning the security to the lender, typically by purchasing
equivalent securities on the open market. In general, short-selling is utilized
to profit from an expected downward price movement, or to hedge the risk of a
long position in the same security or in a related security. Although
short-selling serves useful market purposes, it also may be used as a tool for
manipulation. Further, short-selling can increase stock price volatility.

                                      -13-



                SPECIAL NOTE REGARDING FORWARD-LOOKING STATEMENTS

     Some of the statements contained in this prospectus discuss future events
and developments, including our ability to generate revenue, income and cash
flows, or state other "forward-looking" information. We generally identify these
forward-looking statements by using the words "anticipate," "believe,"
"estimate," "expect," and similar expressions. These statements include, but are
not limited to, information about our cash available to fund our future
operations, future enhancements to our products, growth of the in vitro testing
and point-of-care testing markets, completion of the immunochemistry tests
cartridge, and the planned addition of further tests to our menu. Those
statements are subject to known and unknown risks, uncertainties and other
factors that could cause the actual results to differ materially from those
contemplated by the statements. Important factors that may cause actual results
to differ include those set forth under "Risk Factors" beginning on page 5.

     We do not promise to update forward-looking information to reflect actual
results or changes in assumptions or other factors that could affect those
statements.

                                 USE OF PROCEEDS

     We will not receive any of the proceeds from the sale of the shares by the
selling stockholders pursuant to this prospectus. However, we may receive up to
approximately $14.4 million from the exercise of warrants with underlying common
stock registered hereunder. This figure assumes that those warrants are
exercised without using their cashless exercise feature. There is no guarantee
that any warrants will be exercised or that we will receive any proceeds. The
proceeds, if any, would be used for working capital purposes.

                                      -14-



                                    DILUTION

     The selling security holders listed in this prospectus may offer and sell
shares of our common stock for their own account. We will not receive any
proceeds from any such sales.

     Our net tangible book value as of June 30, 2001 was approximately
$7,217,889, or $0.63 per share of common stock. As the shares of common stock
being registered in this prospectus had already been issued in a private
transaction, there is no additional dilution to the net tangible book value per
share of common stock as a result of sales of shares registered in this
registration statement.

                                      -15-



                            SELLING SECURITY HOLDERS

     The following table sets forth certain information regarding the beneficial
ownership of the common stock as of September 30, 2001 by each of the selling
security holders. Unless otherwise indicated below, to our knowledge, all
persons listed below have sole voting and investment power with respect to the
shares of common stock, except to the extent authority is shared by spouses
under applicable law.

     The information included below is based upon information provided by the
selling security holders and by our transfer agent. Because the selling security
holders may offer all, some or none of their common stock, no definitive
estimate as to the number of shares thereof that will be held by the selling
security holders after such offering can be provided. In the following table,
column (A) shows all shares beneficially held by the holder at September 30,

                              PLAN OF DISTRIBUTION

     We are registering the common stock covered by this prospectus for selling
stockholders. As used in this prospectus, "selling stockholders" includes the
donees, pledgees, transferees or others who may later hold the selling
stockholders' shares of common stock registered herein. We will pay the costs,
expenses and fees in connection with registering the common stock, but the
selling stockholders will pay any brokerage commissions, discounts or other
expenses attributable to the sale of common stock.

     The selling stockholders may sell the common stock from time to time in one
or more types of transactions (which may include block transactions), on the
American Stock Exchange, in negotiated transactions, through put or call option
transactions relating to the shares, or a combination of such methods of sale,
at market prices prevailing at the time of sale, or at negotiated prices. Such
transactions may or may not involve brokers or dealers.

     The selling stockholders may effect such transactions by selling shares
directly to purchasers or to or through broker-dealers, which may act as agents
or principals. Such broker-dealers may receive compensation in the form of
discounts, concessions, or commissions from the selling stockholders and/or the
purchasers of shares for whom such broker-dealers may act as agents or to whom
they sell as principal, or both (which compensation as to a particular
broker-dealer might be in excess of customary commissions).

     The selling stockholders and any broker-dealers that act in connection with
the sale of shares might be deemed to be "underwriters" within the meaning of
Section 2(11) of the Securities Act, and any commissions received by such
broker-dealers and any profit on the resale of the shares sold by them while
acting as principals might be deemed to be underwriting discounts or commissions
under the Securities Act. The selling stockholders may agree to indemnify any
agent, dealer or broker-dealer that participates in transactions involving sales
of the shares against certain liabilities, including liabilities arising under
the Securities Act.

     Because selling stockholders may be deemed to be "underwriters" within the
meaning of Section 2(11) of the Securities Act, the selling stockholders will be
subject to the prospectus delivery requirements of the Securities Act. We have
informed the selling stockholders that the anti-manipulative provisions of
Regulation M promulgated under the Exchange Act may apply to their sales in the
market.

     Selling stockholders also may resell all or a portion of the shares in open
market transactions in reliance upon Rule 144 under the Securities Act, provided
they meet the criteria and conform to the requirements of such Rule.

     If a selling stockholder notifies us that they have entered into or will
enter into any material arrangement with a broker or dealer for the sale of
shares of common stock through a block trade, special offering, exchange
distribution or secondary distribution or a purchase by a broker or dealer, a
supplement to this prospectus will be filed, if required, pursuant to Rule
424(b) under the Securities Act, as soon as practicable, but in no event later
than two business days after the arrangement has been entered into. This
supplement will disclose:

     .    the name of each such selling stockholder and of the participating
          brokers or dealers;

     .    the number of shares of common stock involved;

     .    the price at which such shares were or will be sold;

     .    the commissions paid or to be paid or discounts or concessions allowed
          or to be allowed to such brokers or dealers, where applicable;

     .    if applicable, that such brokers or dealers did not and will not
          conduct any investigation to verify the information set out or
          incorporated by reference in this prospectus; and

     .    other facts material to the transaction.

     In addition, if a selling stockholder notifies us that a donee, pledgee or
other transferee intends to sell more than 500 shares of common stock, we will
file a supplement to this prospectus.

                                      -22-

        TOTAL .....................................................   $28,744.08

Item 15.  Indemnification of Directors and Officers.

   Our Amended and Restated Certificate of Incorporation (the "Charter")
provides that we shall indemnify and advance expenses to the fullest extent
permitted by Section 145 of the Delaware General Corporation Law ("DGCL"), as
amended from time to time, to each person who is or was one of our directors or
officers and the heirs, executors and administrators of such a person. Any
expenses, including attorneys' fees, incurred by a person who is or was one of
our directors or officers, and the heirs, executors and administrators of such a
person in connection with defending any such proceeding in advance of its final
disposition shall be paid by us; provided, however, that if the DGCL requires,
an advancement of expenses incurred by an indemnitee in his capacity as a
director or officer, and not in any other capacity in which service was or is
rendered by such indemnitee, including, without limitation, service to an
employee benefit plan, such be made only upon delivery to us of an undertaking
by or on behalf of such indemnitee, to repay all amounts so advanced, if it
shall ultimately be determined that such indemnitee is not entitled to be
indemnified for such expenses. Notwithstanding the aforementioned
indemnification provisions, we may, at the discretion of our Chief Executive
Officer, enter into indemnification agreements with directors or officers.

   Section 145 of the DGCL provides that a corporation has the power to
indemnify any director or officer, or former director or officer, who was or is
a party or is threatened to be made a party to any threatened, pending or
completed action, suit or proceeding, whether civil, criminal, administrative or
investigative, other than an action by or in the right of the corporation, by
reason of the fact that such director or officer or former director or officer
is or was a director, officer, employee or agent of the corporation, against
expenses, including attorneys' fees, judgments, fines and amounts paid in
settlement actually and reasonably incurred by them in connection with such
action, suit or proceeding, if such person shall have acted in good faith and in
a manner reasonably believed to be in or not opposed to the best interests of
the corporation, and, with respect to any criminal action or proceeding,
provided that such person had no reasonable cause to believe his or her conduct
was unlawful, except that, if such action shall be in the right of the
corporation, no such indemnification shall be provided as to any claim, issue or
matter as to which such person shall have been judged to have been liable to the
corporation unless and to the extent that the Court of Chancery of the State of
Delaware, or any court in which such suit or action was brought, shall determine

                                      -3-



upon application that, in view of all of the circumstances of the case, such
person is fairly and reasonably entitled to indemnify for such expenses as such
court shall deem proper.

   The Charter contains a provision to limit the personal liability of our
directors to the fullest extent permitted by Section 102(b)(7) of the DGCL, as
amended. In addition, the Amended and Restated By-Laws provide that we shall
indemnify any person who was or is a party or is threatened to be made a party
to any threatened, pending or completed action, suit or proceeding, whether
civil, criminal, administrative or investigative, other than an action by us or
in our right, by reason of the fact that he is or was one of our directors,
officers, employees or agents, or is or was serving at our request as a
director, officer, employee or agent of another corporation, partnership, joint
venture, trust or other enterprise, against expenses, including attorneys' fees,
judgments, fines and amounts paid in settlement actually and reasonably incurred
by him in connection with such action, suit or proceeding if he acted in good
faith and in a manner he reasonably believed to be in or not opposed to our best
interests, and, with respect to any criminal action or proceeding, had no
reasonable cause to believe his conduct was unlawful.

   As permitted by the DGCL, the Charter provides that, subject to certain
limited exceptions, none of our directors shall be liable to us or our
stockholders for monetary damages for breach of fiduciary duty as a director,
except for liability (1) for any breach of the director's duty of loyalty to us
or our stockholders, (2) for acts or omissions not in good faith or which
involve intentional misconduct or a knowing violation of law, (3) for the
unlawful payment of dividends on or redemption or repurchase of our capital
stock or (4) for any transaction from which the director derived an improper
personal benefit. The effect of this provision is to limit our ability and our
stockholders' ability through stockholder derivative suits on our behalf, to
recover monetary damages against a director for the breach of certain fiduciary
duties as a director, including breaches resulting from grossly negligent
conduct. In addition, the Charter and Amended and Restated By-Laws provide that
we shall, to the fullest extent permitted by the DGCL, indemnify all of our
directors and officers and that we may, to the extent permitted by the DGCL,
indemnify our employees and agents.

Item 17.  Undertakings.

   Insofar as indemnification for liabilities arising under the Securities Act
may be permitted to directors, officers and controlling persons of the
registrant pursuant to the foregoing provisions, or otherwise, the registrant
has been advised that in the opinion of the Securities and Exchange Commission
such indemnification is against public policy as expressed in the Securities Act
and is, therefore, unenforceable. In the event that a claim for indemnification
against such liabilities (other than the payment by the registrant of expenses
incurred or paid by a director, officer or controlling person of the registrant
in the

                                      -4-



successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the registrant will, unless in the opinion of its counsel the
matter has been settled by controlling precedent, submit to a court of
appropriate jurisdiction the question whether such indemnification by it is
against public policy as expressed in the Securities Act and will be governed by
the final adjudication of such issue.

     The undersigned registrant hereby undertakes:

     (1)  To file during any period in which offers or sales are being made, a
          post-effective amendment to this registration statement:

          (1)  To include any prospectus required by Section 10(a)(3) of the
               Securities Act of 1933, as amended (the "Securities Act");

          (2)  To reflect in the prospectus any facts or events arising after
               the effective date of the registration statement (or the most
               recent post-effective amendment thereof) which, individually or
               in the aggregate, represent a fundamental change in the
               information set forth in the registration statement.
               Notwithstanding the foregoing, any increase or decrease in volume
               of securities offered (if the dollar value of the securities
               offered would not exceed that which was registered) and any
               deviation from the low or high end of the estimated maximum
               offering range may be reflected in the form of prospectus filed
               with the Commission pursuant to Rule 424(b) if, in the aggregate,
               the changes in volume and price represent no more than a 20%
               change in the maximum aggregate offering price set forth in the
               "Calculation of Registration Fee" table in the effective
               registration statement, and

          (3)  To include additional or changed material information on the plan
               of distribution not previously disclosed in the registration
               statement or any material change to such information in the
               registration statement.

     (2)  That, for purposes of determining liability under the Securities Act,
          each post-effective amendment shall be deemed to be a new registration
          statement relating to the securities offered, and the offering of the
          securities at that time to be the initial bona fide offering thereof.

     (3)  To remove from registration by means of a post-effective amendment any
          of the securities being registered which remain unsold at the
          termination of the offering.

     (4)  That, for purposes of determining any liability under the Securities
          Act, each filing of the registrant's annual report pursuant to Section
          13(a) or 15(d) of the Securities Exchange Act of 1934 (and, where
          applicable, each filing of an employee benefit plan's annual report
          pursuant to Section 15(d) of the Securities Exchange Act of 1934) that
          is incorporated by reference in the registration statement shall be
          deemed to be a new registration statement relating to the securities
          offered therein, and the offering of such securities at that time
          shall be deemed to be the initial bona fide offering thereof.

     In addition, the undersigned registrant hereby undertakes to provide to the
underwriters at the closing specified in the underwriting agreements,
certificates in such denominations and registered in such names as required by
the underwriters to permit prompt delivery to each purchaser.
