Order HIV 4th Generation Antigen/Antibody TestThe HIV 4th Generation Antigen/Antibody Test is a laboratory blood test that looks for two distinct markers of HIV infection at the same time: antibodies produced by the immune system and the p24 antigen, a protein that forms part of the virus itself. Because it screens for both, this test is often described as a combination or DUO assay, and it narrows the window between potential exposure and reliable detection compared with older antibody-only methods.
About HIV 4th Generation Antigen/Antibody Test in Green
A combination immunoassay that detects HIV antibodies and p24 antigen together.
The test relies on an immunoassay platform that captures both HIV-1 and HIV-2 antibodies and the p24 antigen in a single run. The p24 antigen appears in the blood earlier than antibodies during acute infection, so its inclusion allows the assay to flag some infections that a third-generation antibody-only test would miss.
Third-generation tests detect only HIV antibodies. They remain useful, but they generally require a longer interval after exposure before results become meaningful. The fourth-generation format shortens that interval by adding antigen detection, which is why it is frequently used as a first-line screening tool in many laboratory settings.
A reactive or positive screening result is not, by itself, a diagnosis. Standard practice is to confirm any reactive fourth-generation result with a supplemental assay, such as an HIV-1/HIV-2 antibody differentiation test or a nucleic acid test. A non-reactive result is also interpreted alongside the timing of possible exposure, since no test can detect infection immediately after it occurs.
