The diagnosis of AIDS is mainly based on the results of the blood test for AIDS. The clinical symptoms of AIDS are not really specific, so you cannot infer the presence of AIDS infection from the symptoms. At present, the diagnosis of AIDS is based on HIV antibodies, HIV confirmatory tests, HIV viral load and CD4-T lymphocyte tests. Testing is usually required after the window period to detect the infection. During the window period, a person is infected with HIV but does not have the appropriate HIV antibodies or HIV viral load, which cannot be detected at this time. If the diagnosis of AIDS is clear, standardized anti-HIV treatment is required as soon as possible. Long-term anti-HIV treatment can prevent the body’s immune cells from suffering serious damage, and can also greatly reduce the infectiousness.
