To confirm AIDS infection, initial screening is conducted for HIV antibodies. If the result is positive, further confirmatory tests must be performed at a disease control center. Only if the confirmatory tests are positive can a diagnosis of AIDS be made. Therefore, confirmatory tests are essential to determine the presence of HIV infection. Once an HIV infection is confirmed, it is crucial to start timely and scientifically sound antiretroviral therapy, as well as to ensure proper rest and maintain good health.
