ELISA, like the Western blot test, detects HIV antibodies in your blood. Antibodies are proteins your immune system produces in response to the presence of foreign substances, such as viruses. If you test positive for HIV on the ELISA test, your provider will order the Western blot test to confirm HIV infection.A widely used diagnostic test for AIDS is ELISA (Enzyme linked Immuno-sorbent Assay). Blood samples are tested for antibodies and antigens. Positive ELISA tests are confirmed with Western blot test. The treatment of AIDS is with antiretroviral drugs which are only partially effective. The drugs commonly used are Azidothymidine, Dideoxyinosine etc. ELISA, short for Enzyme-Linked Immunosorbent Assay, is a widely used laboratory technique that detects and measures the presence of specific antibodies or antigens in a sample. It involves the binding of target molecules (antibodies or antigens) to a solid surface, followed by the addition of enzymes or fluorescent markers to generate a detectable signal. ELISA is .

Sandwich ELISA: A sandwich ELISA measures antigen between two layers of antibodies. Enzyme-linked Immunosorbent Assays (ELISAs) combine the specificity of antibodies with the sensitivity of simple enzyme assays. One of the most useful immunoassays is the two-antibody sandwich ELISA which is used to find the antigen concentration in unknown samples.
