Today, let me talk about the AIDS testing methods.

What are the HIV testing methods

The first is antigen detection. P24 antigen was detected by ELISA. The antigen existed in the blood before the antibody appeared in the early stage of H Ⅳ infection. Due to the small amount of p24, the positive rate is usually low. At present, the method of dissociating immune complex or concentrating p24 antigen is used to improve the sensitivity.

Second: test strip detection, AIDS test strip is a new generation of detection reagents developed by colloidal gold immunochromatography technology. It can detect h Ⅳ - 1 / 2 specific antibody in serum or plasma samples. If the operation time is 15 minutes, the action is simple, rapid, accurate and self-contained.

Third: at present, the tests used as diagnostic means mainly include anti HIV antibody test, virus culture, nucleic acid test and antigen test. Among them, the detection of virus antibody is the most commonly used method, which is not only due to the specificity and high sensitivity of this kind of detection, but also relatively simple and mature.
