If you want to test whether you are infected with AIDS, you can go to a regular hospital and register for the infection department or STD clinic, and have your blood tested for HIV antigens and antibodies to determine whether you are infected with AIDS. At present, the majority of hospitals in China test for AIDS antibodies, which belong to three generations of testing. It is recommended to go to the hospital for HIV antibody testing 4 weeks after the high-risk behavior, when the window period has passed, so the test is relatively more accurate and can avoid the existence of false negatives during the window period.
