Diagnosis

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

In England, if you are a woman aged under 25 years old, you may be offered a chlamydia test when you visit some health services, for example a pharmacy or GP. This offer is part of the National Chlamydia Screening Programme (NCSP).

If you're offered a chlamydia test you should consider taking it.

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 at least 1 hour after 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 in 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 you have it less than 2 weeks since you had sex because 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're 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
• you're offered a chlamydia test as part of the NCSP

If you live in England, you're a woman under 25 and sexually active, it's recommended that you have a chlamydia test once a year, and when you have sex with new or casual partners.

If you live in England, you're a man under 25 and sexually active, it's recommended that you have a chlamydia test once a year if you are not using condoms with new or casual partners.

If you have chlamydia, you may be offered another test 3 to 6 months after being treated. This is because young adults who test positive for chlamydia are at increased risk of catching it again.
