Business Wire - September 9, 2003

This is the second claim approved by the FDA for the OraQuick(R) test. In November 2002, the Company received approval for use of the OraQuick(R) test with fingerstick whole blood specimens. The new approval for venipuncture whole blood is expected to expand the use of the test, especially in hospitals where venipuncture whole blood samples are routinely drawn from patients for testing. Sales of the OraQuick(R) test for use with venipuncture whole blood are subject to the completion of final product labeling incorporating this new claim, which is currently under review by the FDA.

"Receiving FDA approval of a venipuncture whole blood claim is another significant step in our quest to make OraQuick(R) the most versatile rapid HIV-1 test available in the U.S. market," said Mike Gausling, Chief Executive Officer of OraSure Technologies. "This approval should help open the door for hospitals to incorporate the OraQuick(R) test more readily when drawing venous whole blood specimens."

OraQuick(R) is the first rapid, point-of-care test approved by the FDA to detect antibodies to HIV-1 in fingerstick and venipuncture whole blood specimens within approximately 20 minutes. OraSure received FDA approval of the OraQuick(R) test for fingerstick whole blood on November 7, 2002. On January 31, 2003, OraSure received a CLIA waiver for the test, permitting its use by more than 180,000 sites in the United States, including outreach clinics, community-based organizations and physicians' offices.

OraSure is completing the clinical trials for usage of the OraQuick(R) device with oral fluid and plasma samples, and expects to file submissions for these claims with the FDA in the near future. In addition, OraSure has completed the necessary clinical trials and filed for FDA approval for use of the OraQuick(R) device to detect antibodies to a second type of the HIV virus, known as HIV-2. This action was taken by OraSure in anticipation of obtaining access to an HIV-2 patent license, either through another party or directly with the holder of certain patents covering the HIV-2 virus.
