Ordinary blood tests cannot detect HIV. These tests have no relevance to AIDS and cannot be used to determine whether there is HIV infection based on abnormalities in the results of these tests. If the antibodies are positive, a confirmatory test will be done, and only if the test is positive will the diagnosis of AIDS be made. For people with positive initial screening, it is necessary to pay attention to the possibility of false positives, so for people with positive initial screening for HIV antibodies, it is always recommended to do a confirmatory test to clarify.
