The indirect ELISA test is the most commonly used method for detecting the presence of antibodies against HIV in blood samples. It works by using a specific antigen to capture the antibodies present in the sample, which are then detected by a secondary antibody that is conjugated to an enzyme. This produces a color change that indicates the presence of HIV antibodies. Agglutination, complement fixation, neutralization, and direct fluorescent-antibody tests are also used for diagnosing HIV/AIDS, but they are less sensitive and specific than the indirect ELISA test.
