Order HIV 4th Generation Antigen/Antibody TestThe HIV 4th Generation Antigen/Antibody Test is a laboratory blood test used to detect evidence of HIV infection. It is often called a DUO test because it looks for two different markers at the same time: antibodies produced by the immune system and the p24 antigen, a protein that forms part of the virus itself.
About HIV 4th Generation Antigen/Antibody Test in Silver Spring
This test belongs to the fourth generation of HIV screening assays, which combine antibody and antigen detection in a single procedure.
Earlier third-generation HIV tests detected only antibodies. Because the body can take time to produce them, a third-generation test may miss an infection during the earliest stage. Fourth-generation tests add p24 antigen detection, which can appear in the blood sooner than antibodies.
The p24 antigen is a structural protein of HIV. It is generally detectable before antibodies develop, so including it narrows the window between potential exposure and the point at which a test can return a reliable result. When antibodies become abundant, they can bind to p24 and reduce its free levels, but the antibody portion of the test continues to provide signal.
A fourth-generation test is a screening tool. A reactive or positive screening result is typically followed by additional testing to confirm the finding and to distinguish between HIV-1 and HIV-2. A non-reactive result generally indicates that no evidence of HIV was found, though timing relative to any exposure matters.
