To summarize, the only blood tests commonly done for STDs test for syphilis, HIV and hepatitis B. A blood test for herpes exists but is seldom done. A good urethral test for gonorrhea and chlamydia exists, but is seldom done in men unless specifically requested.
Some states still require blood tests for venereal diseases, and a few also test for rubella, sickle-cell anemia, and tuberculosis. No state requires mandatory HIV/AIDS testing, but most states require that marriage license applicants be offered such tests or information where they can obtain a test.
