Executive Summary
Firm's Fluorognost HIV-1 immunofluorescent assay (IFA) test is successful in detecting a "set of African AIDS virus variants" termed "Subtype O," VTS announces. At the recent International Conference on AIDS in Yokohama, Japan, researchers from the Centers for Disease Control and Prevention investigated the performance of nine FDA-licensed diagnostic tests to detect the new "Subtype O" strain. Only three of the tests, including VTS' Fluorognost, were able to identify specimens 100% of the time as positive, the firm says. The Fluorognost IFA was the first HIV-1 diagnostic to be marketed as both a screening and confirmation test ("The Gray Sheet" March 2, 1992, p. 9)
