Sex disease treatment
If your sexual history and current signs and symptoms suggest that you have a sexually transmitted disease (STD) or a sexually transmitted infection (STI), laboratory tests can identify the cause and detect coinfections you might also have.

Urine samples. Some STIs can be confirmed with a urine sample.
Fluid samples. If you have open genital sores, your doctor may test fluid and samples from the sores to diagnose the type of infection
