OraSure had received approval in March for a saliva test of HIV-1 that gives quick results. With the latest U.S. Food and Drug Administration approval, OraSure said it plans to market a combined test for use in physicians’ offices and public health clinics as a rapid means of detecting HIV-1 and HIV-2.

Wade King, an analyst with Wells Fargo, noted that the test, which works within 20 minutes and produces results the same day, cuts out laboratory fees, which usually make up about one third of the total cost of testing for the virus.
