Marriage test can check for AIDS. For the wedding test, at present, the main thing is to do the examination of some sexually transmitted diseases, such as hepatitis B, syphilis, AIDS, etc.. For AIDS, if the initial screening of the marriage test is positive, you need to go further to the hospital to confirm the diagnosis, because the positive initial screening has the possibility of false positives and cannot be used as a basis for confirming the diagnosis. If the confirmatory test is also positive, the diagnosis is clear. If the initial screening test is negative, it is recommended that for high-risk groups, the test be repeated after the window period, and if the test is also negative, it can be completely ruled out.
