The Dept. of Health is looking into why hundreds of New Yorkers were informed that they tested positive for HIV infection after an oral exam, when in fact they were HIV negative. The non-infected status was determined by a follow-up blood test that was administered immediately. Still--pretty scary. The State Health Dept. and the CDC are investigating why the OraSure mouth swab tests resulted in an approximate 50% false-positive rate (The FDA's allowable false-positive rate for HIV tests is 2%). The Health Dept. reported that it has suspended use of OraSure as an HIV-infection detector.
