What is meant by ELISA?
When the body is infected with HIV it produces antibodies specific to HIV. The test, called ELISA (Enzyrn Linked Immunosorbent Assay), looks for such antibodies in blood. If antibodies are present, the test gives a result. A positive test has to be confirmed by another test called Western Blot or Immunoflouroscent Assay (IFA). All positive tests by ELISA need not be accurate and hence Western Blot and repeated tests are necessary to confirm a person’s HIV status. A person infected with HIV is termed HIV – positive or seropositive. If a person is highly likely to be infected with HIV and yet both the tests are negative, a doctor may suggest a repetition of the tests after three months or six months when the antibodies are more likely to have developed.
