An ordinary medical checkup is not able to detect AIDS. An ordinary medical checkup is only a health checkup, and only routine items such as blood tests, liver and kidney functions, electrocardiogram, chest X-ray, blood lipids, blood sugar, etc. will be checked. AIDS-related tests are not conducted because AIDS is a private matter and requires the consent of the individual concerned. If you want to be tested for AIDS, you need to be specifically tested for antigenic antibodies to AIDS, and if you are positive, you can be sure that there is an AIDS infection. Once the infection is confirmed, the viral load and CD4 lymphocyte count should also be checked to clarify the status of the patient after being infected, and the patient should be treated with antiviral drugs as soon as possible after the infection is confirmed.
