Getting tested for chlamydia 

The only way to find out if you have chlamydia is to get tested. You can get tested whether or not you have symptoms.

What does the chlamydia test involve?

The recommended tests for chlamydia are simple, painless and generally very reliable.

They involve sending a sample of cells to a laboratory for analysis. You don't necessarily have to be examined by a doctor or nurse first and can often collect the sample yourself.

There are two main ways the sample can be collected:

  • using a swab – a small cotton bud is gently wiped over the area that might be infected, such as inside the vagina or inside the anus
  • urinating into a container – this should ideally be done after at least one or two hours since you last urinated

Men will usually be asked to provide a urine sample, while women will usually be asked to either swab inside their vagina or provide a urine sample.

The results will normally be available after 7 to 10 days. If there's a high chance you have chlamydia – for example, you have symptoms of the infection or your partner has been diagnosed with it and you've had unprotected sex with them – you might start treatment before you get your results.

When should I get tested?

Don't delay getting tested if you think you might have chlamydia. Being diagnosed and treated as soon as possible will reduce your risk of developing any serious complications of chlamydia.

You can get a chlamydia test at any time, although you might be advised to repeat the test later on if it was less than two weeks since you had sex as the infection might not always be found in the early stages.

You should consider getting tested for chlamydia if:

  • you or your partner have any symptoms of chlamydia
  • you've had unprotected sex with a new partner
  • a condom splits while you've having sex
  • you or your partner have had unprotected sex with other people
  • you think you could have a sexually transmitted infection (STI)
  • a sexual partner tells you they have an STI
  • you're pregnant or planning a pregnancy

If you're under 25 years of age and sexually active, getting tested every year or when you change sexual partner is recommended because you're more likely to catch chlamydia.

Where can I get a chlamydia test?

You can get a free, confidential chlamydia test at:

  • a sexual health clinic
  • a genitourinary medicine (GUM) clinic
  • your GP surgery
  • most contraceptive clinics

You can go to whichever place is the most comfortable and convenient for you. Search for your nearest sexual health service and read about what happens at an STI clinic.

You can also buy chlamydia testing kits to do at home, but these aren't always very accurate. If you're considering using one of these tests, speak to your pharmacist or GP for advice.

Young people under 25 years of age can get tested as part of the National Chlamydia Screening Programme (NCSP). This is often in places such as pharmacies, colleges and youth centres. You can find your nearest test centre on the NCSP website.

In some areas, young people can order a postal testing kit online as part of the NCSP. Search for free online tests for under 25s to see if this is available in your area.
