Same-Day STI Testing: When and How

References UK clinical guidance from the NHS, the British HIV Association (BHIVA), and the British Association for Sexual Health and HIV (BASHH). Last updated: April 2026.

Same-day STI testing is available for urgent situations like recent high-risk exposure, acute symptoms, or before a planned medical procedure. Some NHS sexual health clinics and private services offer rapid tests with results within hours, while lab-based tests usually take a few days. Knowing the options helps you get timely care when it matters.

Here’s what to know.

What Tests Give Same-Day Results

  • Rapid HIV test — finger-prick or oral fluid, 15-20 minute results
  • Rapid syphilis test — finger-prick blood, 15-30 minutes
  • Point-of-care chlamydia/gonorrhoea — available at some specialist clinics, 60-90 minutes
  • Microscopy — for trichomoniasis and some other infections, immediate

What Still Takes a Few Days

  • Lab-based chlamydia and gonorrhoea NAAT
  • Herpes PCR swabs
  • Hepatitis B and C
  • Mycoplasma genitalium
  • Confirmatory testing for any positive result

When Same-Day Testing Makes Sense

  • Urgent PEP assessment (within 72 hours of HIV exposure)
  • Acute symptoms needing immediate attention
  • Before a planned medical or dental procedure
  • High anxiety about recent exposure
  • Before starting or continuing PrEP

Walk-In Options

Many NHS sexual health clinics offer walk-in access, meaning you can arrive without an appointment and be tested on the same day. Results for some tests may be available during your visit, while others come later.

Private Same-Day Testing

Private clinics offer convenience and speed for those willing to pay:

  • Same-day appointments
  • Rapid result panels
  • Treatment at the same visit
  • Costs range from £100 to £500+

What to Expect at a Rapid Test

  1. Brief consultation about your symptoms and history
  2. Sample collection (finger-prick blood, urine or swab)
  3. Result within 15-90 minutes depending on test type
  4. Treatment or referral if positive
  5. Follow-up advice

Limitations of Rapid Testing

  • Some tests are less sensitive than lab equivalents
  • Rapid tests may not cover all STIs
  • Positive results often need lab confirmation
  • Window period still applies — testing too early can miss infection
