Sexually transmitted infections (STIs)

What tests do we offer?

Most STIs are asymptomatic. If you have not had a recent screen (or what you might call a test) then we recommend that you arrange one.

A basic STIs screen includes testing for:

  • Chlamydia
  • Gonorrhoea
  • HIV (rapid test)
  • Syphilis (blood test)

In some circumstances we also offer testing for:

  • Hepatitis A
  • Hepatitis B
  • Hepatitis C
  • HIV (non-rapid 4th generation blood test)

For people with certain symptoms we may offer testing for:

  • Herpes
  • Thrush
  • Bacterial Vaginosis
  • Trichomonas Vaginalis


When is the best time for me to have a screen?

The best time for you to be screened depends on the 'window period'. This is the time it takes from catching an infection (e.g. through unprotected sex) to when the infection would be detected by a test. For example if you have unprotected sex and then have a STI screen one week later for Chlamydia, the test result may be negative. This could be because you did not catch Chlamydia or the test hasn’t detected the infection yet as you are still in the 'window period' for that test. If after two weeks (the window period for Chlamydia) the test result is negative you can be reassured that you did not catch Chlamydia from the unprotected sex two weeks before.

The window period is different for each test:

  • Chlamydia - two weeks
  • Gonorrhoea - one week
  • Trichomonas Vaginalis - two weeks
  • Syphilis - three months
  • HIV (rapid point of care test) - three months
  • HIV (4th Generation non-rapid blood test) - A venous blood sample (e.g from your arm) tested in a laboratory will detect the great majority of individuals who have been infected with HIV at four weeks after the exposure. A negative result on a fourth generation test performed at four weeks post-exposure is highly likely to exclude HIV infection.  A further test at eight weeks post-exposure need only be considered following an event assessed as carrying a high risk of infection.
