What is the Chlamydia/Gonorrhoea (PCR Swab) Test?

The Chlamydia/Gonorrhoea (PCR Swab) test is a molecular diagnostic test that detects the genetic material of Chlamydia trachomatis and Neisseria gonorrhoeae. PCR (polymerase chain reaction) technology allows highly sensitive and specific detection of these infections.

Swab samples can be taken from relevant anatomical sites depending on exposure, including genital, rectal or throat areas. PCR testing can identify infection even when bacterial levels are low, making it the gold standard for STI detection.

This test is widely used in sexual health screening, diagnosis of symptoms and routine STI checks.

Why do I need a test for Chlamydia and Gonorrhoea?

You may need this test if you are sexually active, have symptoms of an STI or have had unprotected sexual contact. Both infections are often asymptomatic but can lead to serious complications if left untreated.

Early detection allows prompt treatment, reduces transmission risk and helps prevent long-term reproductive and systemic health issues.

Symptoms and scenarios where testing is recommended:

• Unprotected sexual contact
• New or multiple sexual partners
• Genital discharge
• Pain or burning during urination
• Pelvic or testicular pain
• Bleeding between periods
• Rectal pain or discharge
• Routine sexual health screening

Step-by-Step: How Testing Works

Choose your preferred testing method

Testing is performed using a swab collected from the relevant site based on exposure.

PCR Swab Collection

1. A clinician collects a swab from the genital, rectal or throat area.
2. The swab is sent to the laboratory.
3. PCR analysis detects bacterial DNA.
4. Results are delivered securely online.

Your Results Explained

Not Detected

No Chlamydia or Gonorrhoea DNA found.
This suggests no active infection at the tested site.

Chlamydia Detected

Chlamydia DNA identified.
Antibiotic treatment is required to clear the infection.

Gonorrhoea Detected

Gonorrhoea DNA identified.
Prompt antibiotic treatment and partner notification are advised.

Positive results should be managed according to UK sexual health guidelines.
