                                  RISK FACTORS

      You should  carefully  consider the risks described below before making an
investment decision.  The risks described below are not the only ones facing our
company.  Additional  risks not presently  known to us or that we currently deem
immaterial may also impair our business operations.

      Our  business,  financial  condition  or  results of  operations  could be
materially  adversely  affected by any of these risks.  The trading price of our
common stock could  decline due to any of these  risks,  and you may lose all or
part of your investment.

      This  prospectus  also contains  forward-looking  statements  that involve
risks and  uncertainties.  Our actual results could differ materially from those
anticipated in these forward-looking  statements as a result of certain factors,
including  the  risks  faced  by  us  described  below  and  elsewhere  in  this
prospectus.

WE FACE INTENSE COMPETITION FROM NEW AND EXISTING DIAGNOSTIC PRODUCTS.

      The diagnostic industry is focused on the testing of biological  specimens
in a laboratory  or at the point of care and is highly  competitive  and rapidly
changing.   Our  principal  competitors  have  considerably  greater  financial,
technical,  and  marketing  resources.  As new  products  enter the market,  our
products may become obsolete or a competitor's products may be more effective or
more effectively marketed and sold than ours. If we fail to maintain and enhance
our competitive position,  our customers may decide to use products developed by
competitors which could result in a loss of revenues.

OUR  RESEARCH AND  DEVELOPMENT  EFFORTS MAY NOT SUCCEED OR OUR  COMPETITORS  MAY
DEVELOP MORE EFFECTIVE OR SUCCESSFUL DIAGNOSTIC PRODUCTS.

      In order to remain competitive,  we must commit substantial resources each
year to research and development. The research and development process generally
takes a significant  amount of time from inception to commercial product launch.
This process is conducted  in various  stages,  and during each stage there is a
substantial  risk that we will not  achieve our goals and will have to abandon a
product in which we have invested  substantial amounts. We expect to continue to
incur  significant costs in our research and development  activities.  Moreover,
there can be no assurance  that we will succeed in our research and  development
efforts.  If  we  fail  to  develop  commercially  successful  products,  or  if
competitors  develop more  effective  products or a greater number of successful
new products, customers may decide to use products developed by our competitors,
which would result in a loss of revenues.

IF  ACCEPTANCE  AND  ADOPTION  OF OUR ORAL FLUID  TESTING IN THE MARKET DOES NOT
CONTINUE, OUR FUTURE RESULTS MAY SUFFER.

      We have made  significant  progress in gaining  acceptance and adoption of
oral fluid testing for HIV in the insurance and public health  markets.  We also
expect that oral fluid  testing for drugs of abuse will be accepted  and adopted
in workplace and criminal justice testing markets.  Other markets,  particularly
the  physician  market,  may resist  the  adoption  of oral  fluid  testing as a
replacement  for other testing  methods in use today.  There can be no assurance
that we will be able to expand use of our oral fluid  testing  products in these
or other markets.

WE MAY REQUIRE FUTURE ADDITIONAL FUNDING TO STAY IN BUSINESS.

      Although we have made significant  progress in the past toward controlling
expenses and increasing  product revenue,  we have historically  depended,  to a
substantial  degree, on capital raised through the sale of our equity securities
to fund our  operations.  Our future  liquidity  and capital  requirements  will
depend on numerous  factors,  including the costs and timing of the expansion of
our manufacturing  capacity, the success of our product development efforts, the
costs and timing of expansion of our sales and marketing activities,  the extent
to  which   existing  and  new  products  gain  market   acceptance,   competing
technological  and market  developments,  and the scope and timing of  strategic
acquisitions.  If  additional  financing  is needed,  we may seek to raise funds
through  the sale of our  equity  securities.  There  can be no  assurance  that
financing  through  the sale of our equity  securities,  or  otherwise,  will be
available on satisfactory terms, if at all.

                                       2


OUR  FAILURE  TO  MAINTAIN  EXISTING   DISTRIBUTION   CHANNELS  OR  DEVELOP  NEW
DISTRIBUTION CHANNELS, MAY RESULT IN LOWER REVENUES.

      We have marketed  many of our products by  collaborating  with  diagnostic
companies and distributors.  For example,  our OraSure Western blot confirmatory
tests are distributed through Organon Teknika Corporation,  and our OraSure oral
fluid collection  device is distributed to the insurance  industry through major
insurance testing laboratories.  Our sales depend to a substantial degree on our
ability to develop product distribution  channels and on the marketing abilities
of the companies with which we collaborate.  There can be no assurance that such
companies  will  continue  to be able to  distribute  our  products  or that new
distribution channels will be available on satisfactory terms.

THE  SIGNIFICANT  TIME  NECESSARY  FOR  REGULATORY  APPROVAL  OF NEW  DIAGNOSTIC
PRODUCTS MAY PREVENT OR ADVERSELY  DELAY OUR ABILITY TO BRING THESE  PRODUCTS TO
MARKET.

      We are  subject  to  strict  governmental  controls  on  the  development,
manufacture, labeling, distribution and marketing of our products. We often must
obtain and maintain  regulatory approval for a product from a country's national
health or drug regulatory  agency before our product may be sold in a particular
country.  The submission of an  application  to a regulatory  authority does not
guarantee that it will grant us a license to market the product.  Each authority
may  impose its own  requirements  and delay or refuse to grant  approval,  even
though our product has been approved in another country.

      In our principal  markets,  the approval  process for a new product can be
complex and lengthy.  The time taken to obtain approval varies  depending on the
nature of the application and may result in the passage of a significant  period
of time from the date of submission of the application. This time span increases
our  costs to  develop  new  products  and  increases  the risk that we will not
succeed in introducing or selling them.

      In  addition,  the  European  Union has  established  a  requirement  that
diagnostic  medical  devices  used to test  biological  specimens  must  receive
regulatory approval known as a CE mark by December 2003. After that date, export
to the  European  community  of products  without the CE mark will be stopped or
delayed  until the mark is received.  This  requirement  will affect many of our
products.  We will not be permitted  to sell our products in European  countries
without a CE mark after  December 2003,  which could lead to the  termination of
strategic  alliances for sales of those  products in Europe.  While we intend to
apply for CE marks for certain of our existing and future products,  and are not
aware of any material  reason why such approvals will not be granted,  there can
be no assurance that any CE marks will be received prior to the deadline.

EVEN THOUGH WE EXPECT TO BE PROFITABLE IN 2001, WE HAVE A HISTORY OF LOSSES.

      We  have  not   achieved   profitability.   We  incurred  a  net  loss  of
approximately  $12.7  million and $4.2 million for the years ended  December 31,
2000 and 1999, respectively,  and as of December 31, 2000, we had an accumulated
deficit of approximately $122.4 million.

      Our limited combined  operating history makes it difficult to forecast our
future  operating  results.  In order to achieve  profitability in the estimated
time period,  our revenue will have to continue to grow at the estimated  rates.
Our  ability to reach our  estimated  revenue  growth will be  dependent  upon a
number of factors  including  achieving growth in international  markets through
our OraQuick  rapid HIV test,  our ability to create market  acceptance  for the
Intercept drugs of abuse products and our ability to commercially  develop,  and
obtain  regulatory  approval and create  market  acceptance  for,  up-converting
phosphor  technology  ("UPT") and other products in a time frame consistent with
our objectives.  We have not yet achieved these objectives. In the event that we
cannot  create a  significant  commercial  market  for our  OraQuick  test,  the
Intercept and UPT products or our other products,  our revenue, and consequently
profitability,  will be lower than estimated.  Even if we achieve profitability,
we cannot assure you that we will be able to sustain such  profitability  in the
future.

                                       3




THE FDA MAY REQUIRE US TO SUSPEND  PRODUCTION OF OUR PRODUCTS WHICH COULD RESULT
IN A LOSS OF REVENUES.

      We can manufacture and sell many of our products,  both in the U.S. and in
some cases abroad,  only if we comply with regulations of governmental  agencies
such  as the  United  States  Food  and  Drug  Administration  ("FDA").  We have
implemented quality assurance and other systems that are intended to comply with
such applicable regulations.  The FDA has issued warning letters and a letter of
intent to revoke our license  with respect to the serum  Western  Blot  product,
stating  that we are not in  compliance  with  the  FDA's  regulations.  We have
responded to each of these  letters.  Although we believe that we are addressing
all  of  the  points  raised  by  the  FDA,  the  FDA  could  force  us to  stop
manufacturing  products  if the  FDA  concludes  that  we  still  remain  out of
compliance with applicable regulations.  In addition,  until the FDA agrees that
we have resolved all of the points raised in their  letters,  we may not be able
to obtain regulatory clearance certificates needed in certain foreign countries.

GOVERNMENT REGULATIONS COULD ADVERSELY AFFECT OUR BUSINESS.

      Many of our proposed and existing  products are subject to  regulation  by
the FDA and other  governmental  agencies.  The  process of  obtaining  required
approvals from these agencies  varies  according to the nature of, and uses for,
our  specific  product  and can  involve  lengthy and  detailed  laboratory  and
clinical  testing,  sampling  activities,   and  other  costly,   time-consuming
procedures.  Changes  in  government  regulations  could  require  us to undergo
additional trials or procedures,  or could make it impractical or impossible for
us to market our products for certain uses, in certain markets, or at all. Other
changes in  government  regulations,  such as the adoption of the FDA's  Quality
System  Regulation,  may not affect our products directly but may,  nonetheless,
adversely affect our financial  condition and results of operations by requiring
that we incur the expense of  changing or  implementing  new  manufacturing  and
control procedures.

A MARKET FOR OUR PRODUCTS MAY NOT DEVELOP.

      Our future success will depend, in part, on the market acceptance, and the
timing of such  acceptance,  of our  recently  introduced  products  such as the
Intercept  oral fluid drug test  service,  the  OraQuick  rapid oral fluid test,
products  currently  under  development  such as UPlink and other products using
up-converting  phosphor technology,  and other new products or technologies that
may be developed or acquired and  introduced  in the future.  To achieve  market
acceptance,  we must make substantial  marketing  efforts and spend  significant
funds to inform  potential  customers  and the public of the  benefits  of these
products.  We currently  have  limited  evidence on which to evaluate the market
reaction to products that may be developed,  and there can be no assurance  that
any products will meet with market  acceptance  and fill the market need that is
perceived to exist.

OUR SUCCESS DEPENDS ON OUR ABILITY TO PROTECT OUR PROPRIETARY TECHNOLOGY.

      The  diagnostics  industry  places  considerable  importance  on obtaining
patent,  trademark,  and trade secret protection,  as well as other intellectual
property  rights,  for new  technologies,  products and  processes.  Our success
depends,  in part, on our ability to develop and maintain a strong  intellectual
property portfolio of products and technologies both in the United States and in
other countries.

      As appropriate,  we intend to file patent  applications  and obtain patent
protection for our proprietary technology. These patent applications and patents
will cover, as appropriate,  compositions of matter for our products, methods of
making those products,  methods of using those products,  and apparatus relating
to the use or manufacture of those products. We will also rely on trade secrets,
know-how and continuing  technological  advancements  to protect our proprietary
technology.  We have  entered and will  continue  to enter into  confidentiality
agreements with our employees, consultants, advisors and collaborators. However,
these  parties  may  not  honor  these  agreements  and we may  not be  able  to
successfully protect our rights to unpatented trade secrets and know-how. Others
may independently develop substantially  equivalent proprietary  information and
techniques or otherwise gain access to our trade secrets and know-how.

      Many of our scientific and management  personnel were previously  employed
by competing  companies.  Although we encourage and expect all of these types of
employees  to  abide by any  confidentiality  agreement  with a prior  employer,
competing  companies  may allege  trade  secret  violations  and similar  claims
against us.

                                       4

      To  facilitate   development  and   commercialization   of  a  proprietary
technology base, we may need to obtain licenses to patents or other  proprietary
rights from other  parties.  If we are unable to obtain these types of licenses,
our product development and commercialization efforts may be delayed.

      We  may  collaborate   with   universities   and   governmental   research
organizations which, as a result, may acquire part of the rights to any
inventions or technical information derived from collaboration with them.

      We may incur substantial costs in asserting or protecting our intellectual
property  rights,  or in  defending  suits  against us  related to  intellectual
property  rights.   Disputes  regarding   intellectual   property  rights  could
substantially  delay  product  development  or   commercialization   activities.
Disputes regarding  intellectual  property rights might include state or federal
court litigation as well as patent interference,  patent  reexamination,  patent
reissue,  or trademark  opposition  proceedings  in the United States Patent and
Trademark Office.  Opposition or revocation proceedings could be instituted in a
foreign  patent  office.  An  adverse  decision  in  any  proceeding   regarding
intellectual property rights could result in the loss of our rights to a patent,
an invention, or trademark.

THE SALES  POTENTIAL  FOR  ORAQUICK  WILL BE  AFFECTED  BY OUR ABILITY TO OBTAIN
CERTAIN LICENSES.

      There are several factors that will affect the specific countries in which
we will be able to sell our OraQuick  rapid HIV test and  therefore  the overall
sales  potential of the test.  One factor is whether we can arrange a sublicense
or distribution  agreement  related to patents for detection of the HIV-2 virus.
HIV-2 is a type of the HIV virus  estimated to  represent  less than 2% of known
HIV  cases  worldwide.  Nevertheless,  HIV-2 is  considered  to be an  important
component in the testing  regimen for HIV in many markets.  HIV-2 patents are in
force in most of the countries of North America and Western  Europe,  as well as
in Japan, Korea, South Africa and Australia. Access to a license for one or more
HIV-2  patents  may be  necessary  to sell HIV-2 tests in  countries  where such
patents are in force,  or to manufacture in countries  where such patents are in
force and then sell into non-patent markets. Since HIV-2 patents are in force in
the U.S., we may be restricted from manufacturing our OraQuick rapid HIV test in
the U.S. and selling into other  countries,  even if there were no HIV-2 patents
in those other countries.

      The  importance of HIV-2  differs by country,  and can be affected by both
regulatory  requirements and by competitive  pressures.  In most countries,  any
product  used to screen the blood  supply  will  require  the  ability to detect
HIV-2,  although  the  OraQuick  rapid HIV test has not been  intended  for that
market  purpose.  In other  markets,  including the U.S., a test that can detect
only the more prevalent HIV-1 type is generally considered sufficient, except in
testing  related to blood  supply.  Because the  competitive  situation  in each
country will be affected by the  availability of other testing  products as well
as the country's regulatory environment, we may be at a competitive disadvantage
in some markets without an HIV-2 product even if HIV-2 detection is not required
by regulations.

      Another factor that may affect the specific  countries in which we will be
able to sell our  OraQuick  rapid HIV test,  and  therefore  the  overall  sales
potential,  concerns  whether  we  can  arrange  a  sublicense  or  distribution
agreement  related to any patents  which claim  lateral  flow assay  methods and
devices  covering the OraQuick rapid HIV test or its use. The OraQuick rapid HIV
test is an  analyte-specific  lateral  flow  assay  device.  There are  numerous
patents in the U.S. and other  countries  which claim lateral flow assay methods
and devices that are analyte  independent.  Some of these patents  broadly cover
the type of  technology  used in the OraQuick  assay and are in force in the U.S
and other  countries.  We may not be able to make the OraQuick rapid HIV test in
the U.S.  and sell it in  countries  where there is no patent on the device.  We
have licenses under several  lateral flow patents and are  considering  the need
for licenses under others.

      In the event  that it is not  possible  to  negotiate  a license  or other
agreement under a necessary  patent, we may be able to modify the OraQuick rapid
HIV test such that a license would not be necessary.  However,  this alternative
could delay  introduction of the OraQuick rapid HIV test into the U.S. and other
markets.

IF WE LOSE OUR KEY  PERSONNEL  OR ARE  UNABLE TO ATTRACT  AND  RETAIN  QUALIFIED
PERSONNEL AS NECESSARY,  OUR DIAGNOSTIC  PRODUCT  DEVELOPMENT  PROGRAMS COULD BE
DELAYED OR HARMED.

      Our success  will depend to a large extent upon the  contributions  of our
executive  officers,  management,  and scientific  staff.  We may not be able to
attract  or  retain  qualified  employees  in the  future  due  to  the  intense
competition for qualified personnel among medical products businesses. If we are
not able to  attract  and retain  the  necessary  personnel  to  accomplish  our
business  objectives,  we may experience  constraints that will adversely affect

                                       5


our ability to meet the demands of our strategic partners in a timely fashion or
to support internal research and development  programs.  In particular,  product
development  programs depend on the ability to attract and retain highly skilled
scientists,   including   molecular   biologists,   biochemists  and  engineers.
Recruiting   qualified   personnel   can  be  an   intensely   competitive   and
time-consuming process.  Although we believe we will be successful in attracting
and retaining qualified  personnel,  competition for experienced  scientists and
other  technical  personnel  from  numerous  companies  and  academic  and other
research institutions may limit our ability to do so on acceptable terms. All of
our employees,  other than a few senior officers who have employment agreements,
are at-will employees,  which means that either the employee or we may terminate
their  employment  at any time. If we  experience  difficulty in recruiting  and
retaining qualified personnel,  and in particular scientific  personnel,  we may
need to provide higher compensation to such personnel than currently anticipated
or we may incur additional expenses for the recruitment of qualified personnel.

      Our  business  plans  will  require   additional   expertise  in  specific
industries  and  areas   applicable  to  the  development   efforts  related  to
up-converting phosphor technologies.  These activities will require the addition
of new  personnel,  including  management,  and the  development  of  additional
expertise by existing  management  personnel.  The  inability  to acquire  these
services or to develop this expertise could impair the  development,  if any, of
products related to this technology.

OUR INCREASING INTERNATIONAL PRESENCE MAY BE AFFECTED BY REGULATORY, CULTURAL OR
OTHER RESTRAINTS.

      We intend to devote significant resources to increase  international sales
of our  OraQuick  and UPT  products.  However,  in the  past,  we  have  not had
significant  direct  experience  with the  governmental  regulatory  agencies in
foreign countries that control sale of products into those countries. Compliance
with  foreign   regulatory   requirements   can  be  difficult  and  can  impede
international marketing efforts. In addition to economic and political issues, a
number of factors  can slow or prevent  international  sales,  or  substantially
increase the cost of international sales, including those set forth below:

o           Regulatory   requirements   (including  compliance  with  applicable
            customs  regulations)  may slow,  limit,  or prevent the offering of
            products in foreign jurisdictions;

o           Cultural  and  political   differences  may  make  it  difficult  to
            effectively  market, sell and gain acceptance of products in foreign
            jurisdictions;

o           Inexperience in international  markets may slow or limit our ability
            to sell products in foreign countries;

o           Exchange rates, currency  fluctuations,  tariffs and other barriers,
            extended  payment  terms  and  dependence  on  and  difficulties  in
            managing  international  distributors or representatives  may affect
            our revenues even when product sales occur; and

o           The  credit-worthiness  of foreign  entities may be less certain and
            accounts receivable collection may be more difficult.

      We recently  entered into a contract for the manufacture and supply of the
OraQuick  HIV device in Thailand.  However,  we do not have  significant  direct
experience with the use of international manufacturers. Factors such as economic
and political conditions and foreign regulatory requirements may slow or prevent
the  manufacture  of our  products in  countries  other than the United  States.
Interruption  of the supply of our products could reduce revenues or cause us to
incur significant additional expense in finding an alternative source of supply.

WE MAY BE SUED FOR PRODUCT  LIABILITIES  FOR INJURIES  RESULTING FROM THE USE OF
OUR DIAGNOSTIC PRODUCTS.

      We may be held liable if any of our products, or any product which is made
with the use or incorporation of any of our  technologies,  causes injury of any
type or is found otherwise  unsuitable  during product  testing,  manufacturing,
marketing or sale. Although we have obtained product liability  insurance,  this
insurance  may not fully cover  potential  liabilities.  As new products come to
market,  we may need to increase our product  liability  coverage.  Inability to
obtain  sufficient  insurance  coverage at an  acceptable  cost or  otherwise to
protect against  potential product liability claims could affect our decision to
commercialize  products  that we  develop  independently


                                       6


or with our  strategic  partners.  If we are sued for any  injury  caused by our
products, our liability could exceed our policy limits.

WE MAY NOT BE ABLE TO  COMMERCIALIZE  OUR UPT  PRODUCTS  WHICH COULD  NEGATIVELY
AFFECT OUR FUTURE REVENUES.

      Our up-converting  phosphor technology is new and is in the early stage of
development.  Commercial  development of UPT may not be  successful.  Successful
products require significant  development and investment,  including testing, to
demonstrate   their   cost-effectiveness   or  other  benefits  prior  to  their
commercialization. In addition, regulatory approval must be obtained before most
products  based upon UPT may be sold.  Additional  development  efforts on these
products  will be required  before any  regulatory  authority  will review them.
Regulatory  authorities  may not approve  these  products for  commercial  sale.
Accordingly, because of these uncertainties,  products based upon UPT may not be
commercialized.  The failure to develop UPT products with  commercial  potential
would negatively affect our future revenues.

WE  ARE  DEPENDENT  UPON   STRATEGIC   PARTNERS  TO  ASSIST  IN  DEVELOPING  AND
COMMERCIALIZING SOME OF OUR DIAGNOSTIC PRODUCTS.

      Although we intend to pursue  some  product  opportunities  independently,
opportunities   that  require  a  level  of  investment  for   development   and
commercialization  may necessitate  involving one or more strategic partners. In
particular,  our  strategy  for  development  and  commercialization  of UPT and
certain other products may entail  entering into  additional  arrangements  with
corporate partners, universities,  research laboratory licensees, and others. If
we are not able to enter into such arrangements,  we may be required to transfer
material  rights to such strategic  partners,  licensees,  and others.  While we
expect that our current and future partners, licensees, and others have and will
have  an  economic   motivation  to  succeed  in  performing  their  contractual
responsibilities,  the  amount and  timing of  resources  to be devoted to these
activities will be controlled by others. Consequently, there can be no assurance
that any revenues or profits will be derived from such arrangements.

WE ARE DEPENDENT UPON PATENTS,  LICENSES AND OTHER PROPRIETARY RIGHTS FROM THIRD
PARTIES,  INCLUDING RIGHTS TO UP-CONVERTING PHOSPHOR  COMPOSITIONS,  METHODS AND
APPARATUSES.

      We  have  licensed  the  worldwide   rights  to   up-converting   phosphor
compositions, methods, and apparatuses for use in diagnostic applications, which
are the subject of seven issued U.S.  patents,  and of one pending  U.S.  patent
application.  Corresponding patents and patent applications have been granted or
issued  in  numerous  foreign  countries,   including,  for  example,   European
countries,  Japan, and Canada.  We cooperate with the licensor to prosecute such
patent applications and protect such patent rights. If the licensors do not meet
their obligations under the license  agreements or do not reasonably  consent to
sublicenses by us, or if the license agreement is terminated,  we could lose the
opportunity to develop the up-converting phosphor technology.

                SPECIAL NOTE REGARDING FORWARD-LOOKING STATEMENTS

      Because  we  want  to  provide  you  with  more   meaningful   and  useful
information,  this prospectus contains,  and incorporates by reference,  certain
forward-looking  statements that reflect our current expectations  regarding our
future  results of  operations,  performance  and  achievements.  We have tried,
wherever possible, to identify these  forward-looking  statements by using words
such as "anticipates,"  "believes,"  "estimates," "expects," "plans," "intends,"
"may,"  "will,"  "should,"  "could" and similar  expressions.  These  statements
reflect our current beliefs and are based on information  currently available to
us.  Accordingly,  these statements are subject to certain risks,  uncertainties
and  contingencies,  including  the factors  set forth  under the caption  "Risk
Factors," which could cause our actual results,  performance or achievements for
2001 and beyond to differ materially from those expressed in, or implied by, any
of these statements.  You should not place undue reliance on any forward-looking
statements.  Except  as  otherwise  required  by  federal  securities  laws,  we
undertake no obligation to release  publicly the results of any revisions to any
such  forward-looking   statements  that  may  be  made  to  reflect  events  or

unanticipated events.

                                   WHO WE ARE

      We develop,  manufacture and market oral fluid specimen collection devices
using our proprietary oral fluid technologies,  proprietary  diagnostic products
including in vitro diagnostic  tests, and other medical devices.  These


                                       7


products are sold in the United States and certain  foreign  countries to public
and  private-sector  clients,  clinical  laboratories,  physician  offices,  and
hospitals, and for workplace testing.

      Our business focuses on the following principal platform technologies: (1)
the  OraSure(R)  oral  fluid  collection   device,  (2)  the  OraQuick(R)  rapid
diagnostics test device, and (3) the new up-converting  phosphor technology,  or
UPT(TM),  including its first  application,  UPlink(TM),  a lateral flow testing
system for various  analytes.  In  addition,  the Company  sells  certain  other
products, including the Histofreezer(R) cryosurgical system, certain immunoassay
tests and  reagents  for  insurance  risk  assessment  and  forensic  toxicology
applications,  an oral fluid Western Blot  confirmatory  test for HIV-1, and the
Q.E.D.(R) Saliva Alcohol Test.

      Our  company  was  formed in May 2000  under  Delaware  law solely for the
purposes of combining two companies,  STC Technologies,  Inc. and Epitope, Inc.,
and changing the state of incorporation of Epitope from Oregon to Delaware.  STC
Technologies and Epitope were merged into our company on September 29, 2000. Our
principal  offices are located at 150 Webster  Street,  Bethlehem,  Pennsylvania
18015, and our telephone number is (610) 882 -1820.

      The merger is expected to leverage our expertise in oral fluid technology,
infectious  disease  testing and substance  abuse testing.  By building upon the
complementary  product  portfolios,  technologies and sales  infrastructures  of
Epitope  and STC  Technologies,  we intend to open up new  markets in the United
States and other  countries and  strengthen  our position in key markets such as
the rapidly  expanding  point-of-care  market.  In particular,  the  proprietary
up-converting phosphor technology has broad applications for oral fluid testing.
With the increased  sensitivity and accuracy of this  technology,  we believe we
can continue to expand the menu of tests available for oral fluid  point-of-care
testing.  This same  basic  technology  is also  expected  to be of  significant
benefit  to  other  medical  diagnostic   manufacturers  outside  the  expertise
contributed  by  Epitope  and STC  Technologies.  For many of  these  additional
applications,  we plan to license these to other companies to provide an ongoing
revenue stream of research and development,  product supply and license fees and
royalties.

                                 USE OF PROCEEDS

      We will not receive any proceeds from the sale by the selling stockholders
of our common  stock.  The  selling  stockholders  will  receive  all of the net
proceeds from the sale of the shares.

pursuant to this  prospectus.  We may amend or supplement  this  prospectus from
time to time to update the  disclosure  set forth  herein.  Because  the selling
stockholders  may from time to time offer all or some of the shares  pursuant to
this offering,  and because there are currently no agreements,  arrangements  or
understandings  with  respect to the sale of any of the shares that will be held
by the selling stockholders after completion of the offering, we cannot estimate
the number of the shares  that will be held by the  selling  stockholders  after
completion of the offering.  However,  for purposes of the table below,  we have
assumed that,  after  completion of the offering,  none of the shares covered by
this prospectus will be held by the selling stockholders.

      The following  table sets forth,  to our  knowledge,  certain  information

                              PLAN OF DISTRIBUTION

      The shares covered by this prospectus may be offered and sold from time to
time by the  selling  stockholders.  The term  "selling  stockholders"  includes
partners, pledgees, donees, transferees or other successors-in-interest  selling
shares received after the date of this prospectus from the selling  stockholders
as a pledge, gift, partnership  distribution or other non-sale related transfer.
To the extent required, we may amend and supplement this prospectus from time to
time to describe a specific plan of distribution.

      The selling  stockholders will act independently of us in making decisions
with  respect  to the  timing,  manner  and  size  of  each  sale.  The  selling
stockholders  may make these sales at prices and under terms then  prevailing or
at prices related to the then current market price. The selling stockholders may
also make sales in negotiated transactions, including pursuant to one or more of
the following methods:

      -  purchases  by  a   broker-dealer   as  principal  and  resale  by  such
         broker-dealer for its own account pursuant to this prospectus;

      -  ordinary  brokerage  transactions  and transactions in which the broker
         solicits purchasers;

      -  one or more block  trades in which the  broker-dealer  will  attempt to
         sell the shares as agent but may  position  and resell a portion of the
         block as principal to facilitate the transaction;

      -  an  over-the-counter  distribution  in accordance with the rules of The
         Nasdaq National Market; and

      -  in privately negotiated transactions.

                                       9



In  connection  with  distributions  of the  shares or  otherwise,  the  selling
stockholders may:

      -  enter into hedging  transactions with broker-dealers or other financial
         institutions,  which may in turn engage in short sales of the shares in
         the course of hedging the positions they assume;

      -  sell the shares short and  redeliver the shares to close out such short
         positions;

      -  enter into option or other  transactions  with  broker-dealers or other
         financial  institutions  which  require the  delivery to them of shares
         offered by this prospectus, which they may in turn resell; and

      -  pledge shares to a broker-dealer or other financial institution, which,
         upon a default, they may in turn resell.

      In  addition,  the selling  stockholders  may sell all or a portion of the
shares that qualify for sale pursuant to Rule 144 and 145 of the Securities Act,
as amended, under Rule 144 or 145 rather than pursuant to this prospectus.

      Sales through  brokers may be made by any method of trading  authorized by
any  stock  exchange  or market on which  the  shares  may be listed or  quoted,
including  block  trading  in  negotiated  transactions.  Without  limiting  the
foregoing,  such  brokers  may act as  dealers by  purchasing  any or all of the
shares covered by this prospectus,  either as agents for others or as principals
for their own accounts,  and reselling such shares pursuant to this  prospectus.
The selling  stockholders may effect such transactions  directly,  or indirectly
through  underwriters,  broker-dealers  or  agents  acting on their  behalf.  In
effecting sales,  broker-dealers  or agents engaged by the selling  stockholders
may arrange for other  broker-dealers  to participate.  Broker-dealers or agents
may receive commissions, discounts or concessions from the selling stockholders,
in amounts to be negotiated immediately prior to the sale.

      In  offering  the  shares   covered  by  this   prospectus,   the  selling
stockholders,  and any broker-dealers and any other participating broker-dealers
who  execute  sales  for  the  selling   stockholders,   may  be  deemed  to  be
"underwriters" within the meaning of the Securities Act in connection with these
sales. Any profits realized by the selling  stockholders and the compensation of
such broker-dealers may be deemed to be underwriting discounts and commissions.

      In order to comply with the securities laws of certain states,  the shares
must be sold in those  states only  through  registered  or licensed  brokers or
dealers.  In addition,  in certain states the shares may not be sold unless they
have  been  registered  or  qualified  for  sale in the  applicable  state or an
exemption from the registration or qualification requirement is available and is
complied with.

                                 INDEMNIFICATION

      Delaware law  authorizes a corporation  to limit or eliminate the personal
liability  of its  directors  for  monetary  damages for breach of a  director's
fiduciary  duty of care.  Delaware  law further  enables  corporations  to limit
available relief to equitable remedies such as injunction or rescission.  Absent
the  limitations  authorized by Delaware  law,  directors  are  accountable  for
monetary  damages for conduct  constituting  gross negligence in the exercise of
their duty of care. Our Certificate of Incorporation limits the liability of our
directors to the fullest  extent  permitted by Delaware  law.  Accordingly,  our
directors will not be personally  liable to us or our  stockholders for monetary
damages for breach of a fiduciary  duty as a director,  except for liability for
breach of the duty of loyalty,  for acts or omissions  not in good faith or that
involve  intentional  misconduct  or a knowing  violation  of law,  for unlawful
payments of dividends or unlawful  stock  repurchases or redemptions as provided
in Section 174 of the General  Corporation Law of the State of Delaware,  or for
any transaction in which a director has derived an improper personal benefit.

      Our Bylaws  require us to  indemnify  to the fullest  extent  permitted by
Delaware  law any person who is a party or is  threatened  to be made a party to
any action,  suit or proceeding by reason of the fact that such person is or was
our director,  officer, employee or agent, or is serving as a director, officer,
employee or agent of another enterprise at our request.  Indemnification is not,
however, permitted under the Bylaws unless the person acted in good faith and in
a manner  that such  person  reasonably  believed to be in or not opposed to our
best interests and, with respect to any criminal action or proceeding, that such
person had no reasonable  cause to believe such  person's  conduct was unlawful.
The  Bylaws  further  provide  that we shall not  indemnify  any  person for any
liabilities  or expenses  incurred by such person in connection  with an action,
suit or proceeding by or in the right of OraSure



                                       11


Technologies  in respect of any claim,  issue or matter as to which such  person
shall have been  adjudged to be liable to us, unless and only to the extent that
the court in which the action, suit or proceeding is brought determines that the
person is entitled to indemnity for such expenses. The indemnification  provided
by the  Bylaws is not  exclusive  of any other  rights  to which  those  seeking
indemnification may be otherwise entitled.

      We have  entered  into  indemnification  agreements  with  certain  of our
directors  and officers.  The  indemnification  agreements  provide that we will
indemnify  these  directors and officers  against all  liabilities  and expenses
actually  and  reasonably  incurred  in  connection  with  any  action,  suit or
proceeding  (including an action by or in the right of OraSure  Technologies) to
which any of them is, was or at any time becomes a party, or is threatened to be
made a party,  by reason of their status as a director or officer,  or by reason
of their  serving  or having  served  at the  request  or on  behalf of  OraSure
Technologies as a director, officer, trustee or in any other comparable position
of any other  enterprise to the fullest extent allowed by law. No indemnity will
be  provided  under the  indemnification  agreements  for any  amounts for which
indemnity  is  provided by any other  indemnification  obligation  or  insurance
maintained by us or otherwise.  Indemnity  will not be available to any director
or officer on account of conduct  which is finally  adjudged  by a court to have
been knowingly  fraudulent,  deliberately  dishonest or willful  misconduct.  No
indemnification  will be provided if a final court adjudication  determines that
such  indemnification is not lawful, or in respect of any suit in which judgment
is rendered  against any director or officer for an  accounting  of profits made
from a purchase or sale of  securities of OraSure  Technologies  in violation of
Section  16(b) of the  Exchange  Act or of any similar law, or on account of any
remuneration  paid to any director or officer which is  adjudicated to have been
paid in violation of law.

      We have also obtained director's and officer's liability insurance.

any transaction in which a director has derived an improper personal benefit.

      Our Bylaws  require us to  indemnify  to the fullest  extent  permitted by
Delaware  law any person who is a party or is  threatened  to be made a party to
any action,  suit or proceeding by reason of the fact that such person is or was
our director,  officer, employee or agent, or is serving as a director, officer,

The  Bylaws  further  provide  that we shall not  indemnify  any  person for any
liabilities  or expenses  incurred by such person in connection  with an action,
suit or proceeding by or in the right of OraSure  Technologies in respect of any
claim,  issue or matter as to which such person  shall have been  adjudged to be
liable to us,  unless and only to the extent that the court in which the action,
suit or  proceeding  is  brought  determines  that the  person  is  entitled  to
indemnity for such expenses.  The indemnification  provided by the Bylaws is not
exclusive  of any other  rights to which those  seeking  indemnification  may be
otherwise entitled.

      We have  entered  into  indemnification  agreements  with  certain  of our

Technologies as a director, officer, trustee or in any other comparable position
of any other  enterprise to the fullest extent allowed by law. No indemnity will
be  provided  under the  indemnification  agreements  for any  amounts for which
indemnity  is  provided by any other  indemnification  obligation  or  insurance
maintained by us or otherwise.  Indemnity  will not be available to any director
or officer on account of conduct  which is finally  adjudged  by a court to have

deliberately  dishonest  or  willful  misconduct.  No  indemnification  will  be

Item 17. Undertakings

      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:

                  (i) To include any prospectus  required by Section 10(a)(3) of
                  the Securities Act;

                  (ii) 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 total dollar
                  value of  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 20%  change in the  maximum  aggregate
                  offering price set forth in the  "Calculation  of Registration
                  Fee" table in the effective registration statement; and

                                       II-2




                  (iii) To include any material  information with respect to the
                  plan  of   distribution   not  previously   disclosed  in  the
                  Registration   Statement  or  any  material   change  to  such
                  information in the Registration Statement;

            provided,  however,  that paragraphs (i) and (ii) above do not apply
            if the  Registration  Statement  is on Form  S-3 or Form S-8 and the
            information required to be included in a post-effective amendment by
            those  paragraphs  is  contained in periodic  reports  filed with or
            furnished to the Commission by the Registrant pursuant to Section 13
            or  Section  15(d) of the  Exchange  Act that  are  incorporated  by
            reference in the Registration Statement.

      (2)  That,  for  the  purpose  of  determining  any  liability  under  the
Securities Act, each such  post-effective  amendment 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.

      (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.

      The  undersigned  Registrant  hereby  undertakes  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 Section 15(d) of the
Exchange Act 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.

      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 SEC such  indemnification  is against
public policy as expressed in the 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  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 of whether
such  indemnification by it is against public policy as expressed in the Act and
will be governed by the final adjudication of such issue.
