The time required for HIV testing varies depending on the type of test, such as antigen-antibody combination test, which starts in 3 weeks and confirms infection in 6 weeks, and antibody test, which starts in 4 weeks and excludes infection in 8 weeks. AIDS is an infectious disease caused by HIV infection, which attacks and destroys the body’s immune system after entering the body, reducing the body’s immunity and inducing various serious diseases. In most patients, HIV antibodies can be detected by reagents after 6 weeks of high-risk sex, and almost all patients can be definitively infected at 12 weeks. Once HIV is clearly infected, systematic and standardized anti-HIV treatment is needed as soon as possible. If early standardized treatment is given to inhibit HIV replication and reproduction in the body, and immunity can be maintained in a normal state for a long time, the survival of the patient can reach a level that is not affected.
