How long STI test results take depends on what’s being tested and where. Rapid tests can give you answers in minutes. Lab-based tests typically take a few days. Postal home kits add a day or two for delivery. Understanding the timelines helps you plan and know what to expect.

Sexual Health Clinic Results

At a UK sexual health clinic, you can usually expect:

  • Rapid HIV result during the visit
  • Other results by text, phone or app within a few days
  • Contact from the clinic if results are positive or need follow-up

Some clinics also offer “point-of-care” testing for a broader panel, giving same-visit results for several infections.

GP Results

If tested at a GP:

  • Samples are sent to a lab
  • Results typically come back within 3-7 days
  • You may need to call or check online for results
  • GP records will include the result

Home Kit Timeline

  1. Order kit — 1-3 days for delivery
  2. Collect sample at home
  3. Post back — 1-2 days
  4. Lab processing — 1-3 days
  5. Results delivered by text, email or secure portal

Total: typically 5-10 days from ordering to results.

When Results Take Longer

  • Weekends and public holidays
  • Postal delays
  • Confirmatory testing for positive results
  • Specialist resistance or subtype testing

What to Do While Waiting

  • Avoid unprotected sex — if positive, you could be transmitting
  • Try not to catastrophise — most results are negative
  • If you have severe or urgent symptoms, don’t wait — contact a clinic
  • Plan when and how you’ll receive the result

What to Do With Positive Results

  • The clinic or service will contact you
  • You’ll be offered treatment, usually at the same clinic
  • Partner notification will be discussed
  • Don’t panic — most STIs are easily treatable

Frequently Asked Questions

Why do some results take longer than others?

Some tests require culture or lab analysis, while others can be done immediately. Postal kits also include delivery time.

Can I get same-day results?

Rapid tests in clinics can give same-day results for HIV and syphilis. Comprehensive panels usually take a few days.

What if I don’t hear back?

Contact the clinic or service. “No news” should not be assumed to mean negative — always follow up.
