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.
You CAN test urine for chlamydia and gonorrhea, but your doctor has to SPECIFICALLY ask for these tests. A special test for DNA will pick up these STD's, and it is NOT performed in a routine check for a urinary tract infection. As a lab tech, let me tell you that I test HUNDREDS of people a day for STD's.
