This test is used for the differential detection of HIV-1 and HIV-2 antibodies (IgG) in human serum or plasma. It is a screening test designed to identify the presence of anti-HIV-1 and anti-HIV-2 antibodies, which are indicative of HIV infection. The test plays a crucial role in the early detection of Acquired Immunodeficiency Syndrome (AIDS) and helps distinguish between HIV-1 and HIV-2 infections.
