Details about Chlamydia/Gonorrhoea PCR (Thin Prep)
What is the Chlamydia/Gonorrhoea PCR (Thin Prep) Test?
The Chlamydia/Gonorrhoea PCR (Thin Prep) test is a molecular diagnostic test that detects Chlamydia trachomatis and Neisseria gonorrhoeae DNA from a Thin Prep liquid-based cytology sample. Thin Prep is commonly used during cervical screening and allows additional testing without collecting a separate swab.
PCR technology provides high sensitivity and specificity, enabling detection of infection even when bacterial levels are low. Using the same Thin Prep sample improves patient convenience and diagnostic efficiency.
This test is widely used in sexual health screening and gynaecological assessments, particularly when STI testing is requested alongside cervical screening.
Why do I need a test for Chlamydia and Gonorrhoea (Thin Prep)?
You may need this test if you are undergoing cervical screening and require STI testing at the same time. Both Chlamydia and Gonorrhoea are frequently asymptomatic but can cause serious reproductive complications if untreated.
Testing via Thin Prep avoids the need for additional swabs, reduces discomfort and ensures accurate detection as part of a comprehensive women’s health assessment.
Symptoms and scenarios where testing is recommended:
- Routine cervical screening with STI assessment
- Unprotected sexual contact
- New or multiple sexual partners
- Abnormal vaginal discharge
- Pelvic pain or discomfort
- Post-coital bleeding
- Fertility investigations
- Sexual health screening without symptoms

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.
