Chlamydia is one of the most common sexually transmitted infections (STIs) in the UK. It's passed on from one person to another through unprotected sex (sex without a condom).  


Most people with chlamydia don't notice any symptoms and don't know they have it. If you develop symptoms, you may experience:

  • pain when urinating
  • unusual discharge from your vagina, penis or rectum (back passage)
  • in women - pain in the tummy, bleeding during or after sex and bleeding between periods
  • in men - pain and swelling in the testicles

Although chlamydia doesn’t always cause any symptoms, if left untreated, the infection can lead to long-term health problems, such as pelvic inflammatory disease (PID), epididymo-orchitis (inflammation of the testicles) and infertility.


The only way to find out if you have chlamydia is to be tested. Testing is free, easy and confidential. We recommend that each time you change your sexual partner you get tested, even if you are using condoms. We strongly advise taking a test if you are aware that a previous sexual partner may have had the infection.

If you are aged 15-24 there is a UK wide chlamydia screening programme which will invite you for regular testing.

Chlamydia testing is available from any of our walk-in and wait and appointment clinics - for men this is a simple urine test and for women usually a self-taken swab. If you fit the criteria* and are happy not to see a health professional you may be offered a fast track test.

All Wirral GPs also offer chlamydia testing.

Aged 16 or over?

An easier way of being tested, if you are aged 16 or over, is to request a free STI postal test kit online. The kit is sent in discreet packaging to an address of your choice. When the kit arrives all you need to do is take a simple urine test or a self-taken swab for women and post it back to us for testing. We text your test result back to you within 7 days. All kits come with all the equipment you need, easy to follow instructions and a freepost envelope to post your sample(s) back to us. 

If you still have symptoms or are worried, you should:

*aged 16 or over, reporting no symptoms and not a man who has sex with men.

**please note our walk-in and wait slots are limited and can, on occasion, incur a 2 hour wait.


If your test is positive we will contact you via your chosen method of communication, usually a text, asking you to call our clinic. Following a discussion with you we will make you an appointment to attend one of our 5 clinic venues.

Chlamydia can be treated easily with antibiotics that we provide for free.

It's important that your current partner and any other recent partners are also tested and treated - we will discuss this with you when you attend clinic and can offer to contact people on your behalf.

It's important when you receive your treatment to not have sex for 7 days, as the antibiotics need time to reach the infection. Our nurse will explain this in more detail.


You can prevent chlamydia and other STIs by:

  • using male condoms or female condoms every time you have vaginal sex or male condoms during anal sex
  • using a condom to cover the penis or a latex or plastic square (dam) to cover the female genitals, if you have oral sex
  • not sharing sex toys or washing them and covering them with a new condom before anyone else uses them
