Let me explain: Standard antibody HIV testing can have two stages. The most commonly used initial screening test is either an enzyme immune assay (eia) or the enzyme-linked immunosorbent assay (elisa). If the eia/elisa test is negative, no additional testing is done. If the eia/elisa screening test is positive, that result must be confirmed with a more specific test called "western blot.".
