It is possible that a blood test may be able to detect AIDS, but it depends on the specific medical test. If the physical examination is only to check the physical condition of a person, it may include blood tests, liver and kidney functions, but not necessarily the HIV antibody test, as it is a contagious disease. If the HIV antibody test is added to the physical examination, the overall cost of the physical examination may be higher, so if there is no requirement for this, then the physical examination will most likely not include the HIV antibody test. In this case, the physical examination will not be able to detect the presence of AIDS. When many units conduct general checkups, antibodies to AIDS or infectious diseases such as hepatitis B, hepatitis C, syphilis, etc. are generally not tested. Therefore, if you want to check whether you have AIDS, you can have a blood test for AIDS antibodies, or if the physical examination does not include this item, you can have your own blood drawn and checked at the hospital.
