How Is STD Testing Done? What to Expect, Step by Step

Updated 2026-11-04

STD testing is usually quick and simple. Most tests use a urine sample, a blood sample or a swab. Here is what typically happens, step by step.

Step by step

  1. Find a location. Choose a clinic in your state or city, or search by ZIP code on our home page. Call to check hours, cost and whether you need an appointment.
  2. Check in. You may fill out a short form. Ask about cost and privacy if you have questions.
  3. Talk with a provider. CDC encourages an open and honest conversation about your sexual history so the provider can recommend the right tests. Questions are routine, not a judgment.
  4. Give samples. CDC says you may need to give blood, urine, or swabs from the vagina, throat or rectum. If you have had oral or anal sex, ask about throat and rectal testing.
  5. Get results. Rapid HIV tests can give results during the visit; lab tests can take several days. The clinic will tell you how you will get results.
  6. Follow up. If a result is positive, many infections can be treated. A positive HIV self-test or rapid test needs a follow-up test to confirm it.

Which tests you may be offered

CDC's general guidelines include: everyone ages 13 to 64 should be tested for HIV at least once; all sexually active women under 25 should be tested for gonorrhea and chlamydia every year; and most sexually active adults should be tested for syphilis based on where they live. Your provider may recommend other tests.
