-CDC Recommends Use of Rapid Testing as Part of Comprehensive HIV 

Testing Strategy-

OraSure Technologies, Inc. (Nasdaq NM:OSUR), the market leader in oral fluid diagnostics, announced today that the Centers for Disease Control and Prevention ("CDC") stated that simple, rapid HIV testing would be a key component to its new HIV testing initiative announced by the CDC on Thursday, April 17, 2003, in the CDC's Morbidity and Mortality Weekly Report ("MMWR") (April 18, 2003 / Vol. 52 / No. 15), and recognized the OraQuick (R)Rapid HIV-1 Antibody Test as the only CLIA (Clinical Laboratory Improvements Amendments of 1988) waived rapid HIV-1 test approved by the FDA.

The new CDC initiative, entitled "Advancing HIV Prevention: New Strategies for a Changing Epidemic," is aimed at making HIV tests a more routine part of medical practice for pregnant women and the estimated 200,000 people in the United States who currently have the HIV virus but may be unaware that they are infected. The initiative expands on current HIV prevention strategies and encourages the more widespread use of rapid HIV testing.

"We applaud the CDC's new HIV testing initiative and are eager to continue working in partnership with the CDC to make rapid HIV testing available to all who need it," said Mike Gausling, President and Chief Executive Officer of OraSure Technologies. "As the only CLIA waived, rapid, point-of-care HIV-1 test, OraQuick(R) will be crucial for HIV testing in non-traditional settings, where simplicity and mobility are critical factors."

"This new initiative is exciting and it capitalizes on new, rapid testing technologies; provides us the opportunity to reduce barriers to testing; enhances prevention services; and continues to prevent mother-to-child HIV infections," said Harold Jaffe, M.D., director of CDC's National Center for HIV, STD, and TB Prevention. (CDC Press Release, 4/17/2003)

The CDC has identified $35 million to support the new HIV testing strategy. As part of this comprehensive initiative, the CDC announced that in 2003 it will fund new demonstration projects using OraQuick(R) to increase access to early diagnosis and referral for treatment and prevention services in high-HIV prevalence settings, including correctional facilities. (MMWR, April 18, 2003)

The initiative has four parts, and will be implemented by several agencies working together within the Department of Health and Human Services. It includes making HIV testing a routine part of medical care; creating new models for diagnosing HIV infections outside medical settings; preventing new infections by working with people diagnosed with HIV and their partners; and further decreasing mother-to-child HIV transmission by incorporating HIV testing in the routine battery of prenatal tests.

On Thursday, April 24, 2003, the CDC hosted a satellite broadcast and web cast entitled, "Update on Rapid Testing for HIV." The 2-hour forum was co-sponsored by the CDC and the Public Health Training Network, and described rapid tests for HIV including availability, administration, benefits and limitations; implementation considerations for counseling and testing; confirmatory testing for positive test results; quality assurance and training; and resources for updates on rapid testing. The broadcast featured presentations, interviews and panel responses to audience questions and a replay may be accessed through a link at http://legacy.cdcnpin.org/broadcast/current/2003/0424/start.htm.

OraQuick(R) is the first FDA-approved rapid, point-of-care test designed to detect antibodies to HIV-1 in finger-stick whole blood within approximately 20 minutes. OraSure received FDA approval of the OraQuick (R)test 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.
