Sexually Transmitted Infection
Also known as a sexually transmitted disease, is an infection passed from one person to another person through sexual contact. An infection occurs when a bacteria, virus, or parasite enters and grows in or on your body.
Diagnosis and Interventions
Testing for STIs is also called STI screening.
STI testing can include:
Pelvic and physical exam. Your doctor looks for signs of infection, such as warts, rashes, or discharge.
Blood test. A nurse will draw some blood to test for an STI.
Urine test. You urinate (pee) into a cup. The urine is then tested for an STI.
Fluid or tissue sample. Your doctor or nurse uses a cotton swab to take fluid or discharge from an infected place on your body. The fluid is looked at under a microscope or sent to a lab for testing.
