Specimens that are reactive on the initial antigen/antibody combination immunoassay and nonreactive or indeterminate on the HIV-1/HIV-2 antibody differentiation immunoassay should be tested with an FDA-approved HIV-1 nucleic acid test (NAT). A reactive HIV-1 NAT result and nonreactive Reactive HIV-1 antibody but positive HIV-2 antibody results usually indicate the presence of HIV-2 infection with HIV-1 antibody cross-reactivity (eg, presence of only HIV-1 gp41 and/or gp160 band). However, such results may be rarely due to HIV-1 and HIV-2 coinfection. HIV-2's closest relative is SIVsm, a strain of SIV found in sooty mangabees. Since HIV-1 is derived from SIVcpz, and HIV-2 from SIVsm, the genetic sequence of HIV-2 is only partially homologous to HIV-1 and more closely resembles that of SIVsm.

This test is for use as the antibody differentiation test in the specific multi-test algorithm. It is not to be ordered as a rapid screen test and cannot be used as a supplemental test if the initial screen test was a rapid test. This test discriminates between HIV-1 and HIV-2 antibodies. Results for each type are reported. This test is for use as the antibody differentiation test in the specific multi-test algorithm. If results are negative or indeterminate, this test does NOT reflex to a nucleic acid test.

If acute or early HIV-2 infection is suspected, detection of HIV-2 DNA/RNA (FHV2Q / HIV-2 DNA/RNA Qualitative Real-Time PCR) is recommended, based on the patient's clinical and epidemiologic exposure history. The HIV antibody test advised by the CDC is the HIV-1/2 antigen/antibody combination immunoassay test. If you test positive for HIV, the CDC advises the following follow-up tests: HIV-1/HIV-2 antibody differentiation immunoassay.
