I believe many friends know that self-cleaning is a good way to prevent AIDS, but experts say that drugs can also be used to prevent AIDS. Now let's learn about AIDS screening? Let's go.

How is HIV screening going on?

First: HIV antibody test in blood or body fluid. It should be tested in the "HIV screening laboratory" officially approved by the health administration. Blood samples were tested for HIV antibody by solid-phase enzyme-linked immunosorbent assay (ELISA). The positive results were suspected to be infected. The test samples should be confirmed by the local "HIV confirmation laboratory" with more reliable Western blot test to determine the specificity of the antibody.

Second: HIV-1 p24 antigen test. There is HIV in the patient's blood, that is, p24 antigen. It can solve the problem of "window period" of antibody examination and get diagnosis earlier.

Third: CD4 lymphocyte count in blood. HIV mainly invades CD4 lymphocytes, invades cells, propagates and destroys these cells with important immune function. As a result, the immune function of patients is damaged due to defects, and a variety of infections occur due to the decline of immune function. Even the normal bacteria, viruses and parasites can be infected with AIDS.
