Jun 27, 2014 · Laboratories should conduct initial testing for HIV with an FDA-approved antigen/antibody combination immunoassay* that detects HIV-1 and HIV-2 antibodies and HIV-1 p24 antigen to test for established HIV-1 or HIV-2 infection and for acute HIV-1 infection. No further testing is required for specimens that are nonreactive on the initial immunoassay. Phương pháp test nhanh HIV Ag/Ab combo bạn nhắc tới cho phép tìm kháng thể virus HIV.
