All tests for HIV antibodies will look for HIV-1, which is more common than HIV-2 in the U.S. Combination tests have been developed to find HIV antibodies and HIV antigens called p24 antigens. The HIV antibody test advised by the CDC is the HIV-1/2 antigen/antibody combination immunoassay test.

One sample, one minute, two results. Two results in as little as 60 seconds. If the HIV-1/HIV-2 antigen/antibody test is positive, an antibody-based HIV-1/HIV-2 test is done (at additional charge) to confirm infection and identify whether it is caused by HIV-1 or HIV-2. However, the HIV-1/HIV-2 differentiation test will be negative during acute infection (prior to development of specific antibodies).

Antibody tests can take 23 to 90 days to detect HIV infection after an exposure. 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. 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. If HIV viral load testing is nonreactive and the HIV-1 and HIV-2 antibody immunoassay results are negative or indeterminate, the initial antigen/antibody combination immunoassay result may be Validation & Qualification Materials.

The protective effect of antibodies is thereby circumvented. In contrast, a vigorous neutralizing antibody response characterizes HIV-2 infection. Neutralization
