What is chlamydia?


Chlamydia is very common, affects the 15-24 age group the most and, as it often has no symptoms, the only way to know if you have it is to test regularly. Testing for chlamydia is really easy - it just involves peeing in a pot or having a swab - and you can order a self test kit online.

Our online service is free and confidential, which means we won’t share any details about your test. You’ll get your results back within 10 working days, straight to your phone.

Chlamydia can be treated very easily by taking a course of antibiotics. However if left untreated it can seriously affect your health in a number of ways:

  • It can cause infertility (this is where you have problems conceiving or are unable to).
  • It can cause reactive arthritis which affects your joints - this can be painful and cause long-term joint problems.

Using condoms also reduces the chances of getting STIs like chlamydia and they can also prevent pregnancy. For more information about where you can get free condoms near you, visit our Service Finder.
