The rules differ from state to state. Many states have done away with mandatory premarital physical exams or blood tests. Some states still require for venereal diseases, and a few also test for rubella (also known as German Measles, a disease that is very dangerous to fetuses), tuberculosis, and sickle-cell anemia. Due to the rise in HIV and AIDS, many states now require that parties applying for a marital license must be offered an HIV test and/or must be provided with information on AIDS and tests available. Presently, no states requires a mandatory premarital HIV/AIDS test.
