HIV quantitative and qualitative tests are equally accurate. HIV testing can be done either quantitatively or qualitatively. HIV-1/2 antibody testing, if positive, requires further confirmatory testing, which is the gold standard for the diagnosis of HIV infection. Quantitative tests can be used to distinguish between strong and weak positivity for HIV antibodies. Currently, the diagnosis of HIV is usually done by qualitative tests, and there is no need to do quantitative tests. As long as the qualitative HIV antibody test is positive, it can be used as the basis for confirmation of the diagnosis. In addition to the qualitative HIV antibody test, the HIV nucleic acid test results can also be used as an adjunctive test, and the nucleic acid test results of the HIV test can also be used as a judgment for treatment. For those who have had unsafe sex, used shared syringes and needles, etc., and suspect that they may have been exposed to HIV, they should actively go to the hospital for examination; for those who have already been diagnosed with HIV, they should also seek medical treatment in a timely manner.
