How long should I wait before I test?

Some infections do not show up immediately after sex and you may need to wait in order to get accurate test results.

We usually say to wait:

  • 2 weeks for chlamydia and gonorrhoea
  • 4 weeks for syphilis and HIV (in some circumstance you also need a test at 3 months)

If you have symptoms of infection, contact us for a telephone appointment; we will probably offer testing sooner.

For other infections, the timings can vary. Please book a telephone appointment to discuss:


Been in contact with HIV? It is important to seek help as soon as possible as you may need post-exposure prophylaxis after sexual exposure (PEPSE). See PEPSE for details.
