Clinical Info

This test is a 4th Generation HIV screening assay used for the diagnosis of Human Immunodeficiency Virus (HIV) and tests for HIV p24 antigen as well as antibodies against both HIV-1 and HIV-2. All reactive HIV screens will reflex automatically to HIV-1/HIV-2 Antibody Supplemental testing to differentiate HIV-1 and HIV-2 antibodies. If supplemental antibody testing is negative, an automatic reflex to HIV-1 Molecular Detection will be performed. If all confirmatory testing is negative, the most likely explanation is a false positive HIV screening result.
