BETHLEHEM, Pa.--(BUSINESS WIRE)--Aug. 2, 2005--OraSure Technologies, Inc. (NASDAQ:OSUR), the market leader in oral fluid diagnostics, announced today that it has received a worldwide, non-exclusive license from Ortho-Clinical Diagnostics and Chiron Corporation to patents relating to the hepatitis C ("HCV") virus. Under the terms of the license, OraSure has obtained non-exclusive rights to certain HCV patents from Ortho-Clinical Diagnostics and Chiron Corporation, in exchange for the payments of upfront fees and ongoing royalties on product sales.

The license will permit OraSure to manufacture, distribute and sell a rapid, point-of-care diagnostic product to detect antibodies to HCV in both oral fluid and blood. There currently is no U.S. Food and Drug Administration ("FDA") approved rapid HCV test in the United States, and there is no rapid HCV test available anywhere in the world that can be used on oral fluid.

"Securing this HCV license gives us the opportunity to pursue and develop a rapid test for hepatitis C, one of the most common chronic bloodborne viral infections in the U.S. and abroad, and one that is seen frequently in patients who also have HIV," said Douglas A. Michels, President and CEO of OraSure Technologies. "Our goal has always been to create the most versatile and comprehensive point-of-care rapid tests in the world, and this license will enable us to expand our product offerings to include HCV diagnostics."

First identified by Chiron scientists in 1987, HCV is the causative agent for what was formerly known as non-A non-B hepatitis. HCV is a major cause of acute hepatitis and chronic liver disease, including cirrhosis and liver cancer. There is no known vaccine to prevent HCV.

Globally, an estimated 170 million persons, or 3 percent of the world's population, are chronically infected with HCV and three to four million people are newly infected each year, according to the World Health Organization.

OraSure, the market leader in oral fluid diagnostics, launched the OraQuick(R) ADVANCE(TM) Rapid HIV-1/2 Antibody Test in October 2004, the first and only FDA-approved and CLIA (Clinical Laboratory Improvements Amendments Act of 1988) waived rapid, point-of-care test that can detect antibodies to both HIV-1 and HIV-2 in 20 minutes, using oral fluid, finger-stick or venipuncture whole blood and plasma specimens. OraSure believes that its OraQuick(R) platform may be used for the diagnosis of other infectious diseases, including HCV.
