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.
Blood was first tested for hepatitis B in 1971 and for HIV in 1985. Today, blood is tested for syphilis, hepatitis C, West Nile virus and other diseases. Blood tests also can help a doctor identify various types of illnesses in patients, including anemia, diabetes and malaria.n the 1930s and 1940s, blood testing to screen for syphilis and/or rubella became a prerequisite for obtaining a marriage license in most states. According to Dr. Robert H. Shmerling of Beth Israel Deaconess Medical Center, sexually transmitted diseases were extremely common in those days.
