Chlamydia trachomatis Screening Test

Chlamydia is one of the most common sexually transmitted infections, caused by the bacterium Chlamydia trachomatis. This test detects the presence of the bacterium from a swab sample. Chlamydia frequently causes no symptoms at all, which means many people carry and pass on the infection without knowing, making testing the only reliable way to know your status.

What it is used for

• Detecting current chlamydia infection from a swab sample
• Testing when you have no symptoms, which is important as chlamydia is often silent
• Checking after a possible exposure or a change of partner
• Confirming clearance after treatment, where advised

Why it matters

Left untreated, chlamydia can lead to more serious problems, including pelvic inflammatory disease, and in some cases can affect future fertility in both women and men. The good news is that it is straightforward to treat with antibiotics once identified. Testing allows for early treatment, protects your long-term health, and helps prevent the infection being passed on to others.

An important note

If your result is positive, it is important to complete the recommended treatment and to avoid sexual contact until treatment is finished, as advised. Recent sexual partners should also be tested and treated to prevent reinfection and onward spread. Any positive result should be discussed with your GP or a sexual health service, who can arrange treatment and appropriate advice.
