Details about Chlamydia/Gonorrhoea PCR (Throat Swab)
What is the Chlamydia/Gonorrhoea PCR (Throat Swab) Test?
The Chlamydia/Gonorrhoea PCR (Throat Swab) test is a molecular diagnostic test that detects the genetic material of Chlamydia trachomatis and Neisseria gonorrhoeae in the throat. PCR technology allows highly sensitive detection, even when bacterial levels are low.
Throat infections with these bacteria are frequently asymptomatic and may go unnoticed without targeted testing. This test is specifically designed to identify oral infections acquired through oral sexual contact.
PCR throat swab testing is considered the gold standard for diagnosing extragenital Chlamydia and Gonorrhoea infections.
Why do I need a test for Chlamydia and Gonorrhoea (Throat Swab)?
You may need this test if you have engaged in oral sex or if routine genital testing has been negative but symptoms persist. Throat infections can act as a reservoir for transmission and may contribute to antibiotic resistance if left untreated.
Testing ensures accurate diagnosis and appropriate treatment, reducing the risk of onward transmission and complications.
Symptoms and scenarios where testing is recommended:
- Oral sexual contact
- Persistent sore throat without clear cause
- Sexual partner diagnosed with an STI
- Routine STI screening with oral exposure
- High-risk sexual behaviour
- Follow-up after previous STI
- Screening in asymptomatic individuals
- Comprehensive sexual health assessment

Step-by-Step: How Testing Works
Sample Collection Method
Testing is performed using a throat swab collected by a clinician.
PCR Throat Swab Process
- A clinician collects a swab from the back of the throat.
- The swab is sent to the laboratory.
- PCR analysis detects Chlamydia and Gonorrhoea DNA.
- Results are delivered securely online.

Follow these guidelines for accurate results
Sample Timing
Where possible, attend your blood test between 7am and 12pm. Please wait until any short-term illness or infection has fully resolved before testing. Avoid intense exercise for 24–48 hours beforehand, as this can affect certain markers.
Fasting & Hydration
Fasting is not always required, but some tests may recommend it. If fasting is advised, avoid food for 8–12 hours before your appointment and drink water only. Stay well hydrated, as this helps with sample collection and accuracy.
Medications & Supplements
Continue prescribed medications unless advised otherwise by your clinician. Avoid vitamin, mineral, or biotin supplements for at least 24–48 hours before your test, as these can interfere with results. If you are unsure about any medication or supplement, please let us know before your appointment.
Hormones & Menstrual Cycle
For hormone-related tests, timing within your menstrual cycle may be important. If relevant, follow any specific guidance provided on your test page.
If you have any questions or special circumstances, our team is happy to advise before your appointment.
