Normal medical checkups are able to detect diseases, but these programs do not include HIV antibodies, and cannot detect the presence of AIDS. The purpose of a normal medical checkup is mostly just to see how well one’s body is doing, and is likely to include only routine blood tests, liver and kidney functions, chest X-rays, ultrasound, and other programs, and does not include tests that can be suggestive of AIDS. Normal medical checkups generally do not include Hepatitis B, Hepatitis C, syphilis, AIDS, etc., which are all infectious diseases that can be transmitted through the sexual or blood route. Most tests are done before blood transfusions or surgery, or before blood donations, and they are not checked for these infectious diseases because they are not included in the physical examination.
