HIV 1 & 2 Screening Test - HIV 1 & 2 Antigen/Antibody Test

A fourth-generation immunoassay (enzyme-linked immunosorbent assay - ELISA), designed for the qualitative detection of HIV-1 and/or HIV-2 antibodies, as well as the virus's p24 antigen, in serum or blood plasma. This fourth-generation assay reduces the diagnostic window (the time between infection and detection) compared to older assays that detect only antibodies.
