Laboratory tests are readily available for the diagnosis of HIV infection. These are based on the detection of HIV-specific antibodies and HIV p24 antigen in combination screening assays, followed by confirmation by Western blot. Managing established HIV infection, including the use of antiretroviral drugs, has been facilitated by the use of nucleic acid tests that measure HIV RNA load in plasma or detect mutations associated with drug resistance. Quality assurance programs ensure high-level performance of HIV assays.
