Chlamydia is one of the most common sexually transmitted infections in the UK, especially in people under 25. It's a bacterial infection that can affect the genitals, throat or rectum. Most people have no symptoms, so testing is often the only way to know.
Most people with chlamydia have no symptoms. When symptoms do occur, they can include:
Chlamydia is easily treated with antibiotics. Left untreated, it can sometimes lead to:
Routine chlamydia testing is suitable from 14 days after exposure. Testing earlier may miss an infection. If you have symptoms or a partner has tested positive, choose GP-led testing rather than waiting.
Chlamydia can affect more than one part of the body. Testing only one sample site can miss an infection elsewhere.
Routine or GP-led testing

A GP will review your result and explain what it means. Chlamydia is treated with a short course of antibiotic tablets, which the GP reviewing your result can usually prescribe. They'll also talk to you about letting recent partners know and whether you need to test again.

FAQs
Answers about when to test, which samples you may need, result times and what happens after a positive result.
Yes. DocTap's routine £74 test checks for both chlamydia and gonorrhoea using a urine sample or genital swab. Throat and rectal samples are separate, and broader STI screens can also include HIV and syphilis.
For routine chlamydia testing, wait at least 14 days after exposure. Testing earlier can miss an infection. If you have symptoms, a partner has tested positive or you are worried about a recent exposure, book a GP-led appointment rather than waiting.
The right sample depends on the type of exposure. A urine sample or genital swab tests the genital area; throat and rectal swabs test those sites separately. If you are unsure which sites to test, book GP-led testing.
A GP will explain your result and can usually prescribe antibiotics. They'll talk to you about letting recent partners know and advise whether you need to test again.
Yes. Most people with chlamydia have no symptoms, so routine testing can detect an infection you may not otherwise know about. If you have symptoms or need clinical advice, book GP-led testing.
It can if it's left untreated. Chlamydia can spread and cause pelvic inflammatory disease, which can affect fertility and increase the risk of ectopic pregnancy. Prompt testing and treatment is the best way to reduce this risk.
Selected tests at DocTap clinics with on-site laboratories have results within 4 hours of the sample being taken, or the test fee is refunded. At our other clinics, most standard results are ready by 6pm the next working day.
No, not always. If you have no symptoms and know you want routine testing, you can book a healthcare assistant-led chlamydia and gonorrhoea test directly at one of our five clinics with on-site laboratories. If you have symptoms, a recent exposure, a partner has tested positive or you are unsure which sample sites to test, book a GP-led appointment instead.
