How does a doctor test for an STI?

Sexually transmitted infections are infections commonly spread by vaginal intercourse, anal sex or oral sex. Many STIs show no symptoms, resulting in passing on the disease to others. STIs can be passed between men and women, women to women or men to men, and if you think you have an STI you should get tested as soon as possible. The sooner you are tested, the sooner the treatment can be started.

The tests are fairly straightforward; you will be asked a number of questions regarding your sexual activity and how many sexual partners you have. Men will have an examination of their genitals, women will have a pelvic examination, and based on these findings, the doctor may take a blood sample, a urine sample, a swab from inside the mouth, a swab from the genital area or a swab of any discharge which is occurring. These tests will be sent away to a laboratory and the results will follow several days later.
