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.
HIV test results can be obtained within three days. Chlamydia and gonorrhea test results take about a week. Tests done to check HIV infection can also provide information regarding the presence of some other STDs in the body. A urine and blood sample is usually taken during STD check-up.
