Routine medical checkups are not able to detect AIDS, because routine medical checkups don’t check for AIDS, they only check for routine blood tests, liver and kidney functions, blood lipids, blood sugar and so on, while AIDS is a private matter, and usually no individual will be checked without his/her permission. Therefore, if you want to check for AIDS, you need to check for antigens and antibodies, and you need to go to the hospital to have your blood tested. Once you are diagnosed as positive, you need to further check for viral load, lymphocyte function, etc., in order to determine what kind of status the patient is in. The next step is to use antiretroviral drugs as soon as possible, to inhibit the replication of the virus, so that the patient’s immune function can be restored.
