Overview of the Chlamydia/Gonorrhoea PCR (Throat Swab)
The Chlamydia/Gonorrhoea PCR (Throat Swab) is a site-specific molecular test used to detect Chlamydia trachomatis and Neisseria gonorrhoeae genetic material in the pharynx.
The test contains 1 combined biomarker: Chlamydia/Gonorrhoea (Throat Swab).
Pharyngeal infection can occur following oral sexual exposure.
Gonorrhoea is particularly important in the throat because pharyngeal Gonorrhoea is frequently asymptomatic. A person may therefore carry and transmit the infection without experiencing a sore throat or any other obvious symptom.
Chlamydia can also be detected in the pharynx, although throat Chlamydia is less common than urogenital infection.
PCR and related nucleic-acid amplification methods provide sensitive detection because they look directly for organism genetic material in the sampled site.
Testing the correct anatomical site is essential.
A negative urine or genital result does not exclude infection in the throat. Similarly, a negative throat swab does not exclude genital or rectal infection.
This is why STI testing should be selected according to actual sexual exposure rather than relying on one specimen type for every body site.
Pharyngeal Gonorrhoea has additional public-health importance because the throat can act as a reservoir for infection and may contribute to transmission.
The PCR result identifies whether Gonorrhoea genetic material is present but does not determine antibiotic susceptibility. Additional culture or other follow-up may therefore be required following a positive Gonorrhoea result.
What Does the Chlamydia/Gonorrhoea PCR (Throat Swab) Test Check?
This test measures 1 combined biomarker.
Chlamydia/Gonorrhoea (Throat Swab)
Detects Chlamydia trachomatis and Neisseria gonorrhoeae genetic material in a throat specimen following relevant oral sexual exposure.
Who May Benefit From the Atypical Pneumonia Screen?
This test may be suitable for people whose clinician is investigating persistent or unusual respiratory symptoms and wants additional information about possible atypical bacterial causes.
Persistent respiratory symptoms - May provide additional laboratory information where coughing, fever or respiratory symptoms have continued longer than expected.
Possible atypical pneumonia - Assesses antibody responses associated with three organisms recognised as causes of atypical respiratory infection.
Prolonged cough - Mycoplasma pneumoniae and Chlamydia pneumoniae can be considered among several possible causes of a persistent cough.
Unexplained fever with respiratory symptoms - Serology may provide supporting information when considered alongside clinical assessment and other investigations.
Possible Mycoplasma pneumoniae exposure - Measures both IgM and IgG antibodies associated with Mycoplasma pneumoniae.
Possible Chlamydia pneumoniae exposure - Measures both IgM and IgG antibodies associated with Chlamydia pneumoniae.
Possible Legionella exposure - Includes Legionella antibody screening within the wider atypical pneumonia assessment.
Respiratory illness that has not followed the expected course - Additional testing may sometimes be considered when symptoms persist despite initial management.
Private specialist respiratory testing - Access the screen through London Blood Tests with clinic and home or hotel phlebotomy options.
How to Prepare
Do not rely on a throat swab to assess infection at other anatomical sites.
If several sites were exposed, appropriate multisite testing provides a more complete assessment than a single specimen.
Symptoms and Reasons to Consider the Chlamydia/Gonorrhoea PCR (Throat Swab) Test
Most pharyngeal Chlamydia and Gonorrhoea infections are asymptomatic, so testing should not depend on throat symptoms being present.
No symptoms after oral sexual exposure - Asymptomatic infection is common, particularly with pharyngeal Gonorrhoea.
Persistent sore throat after relevant sexual exposure - A sore throat is non-specific but may justify STI testing when oral exposure has occurred.
Redness or irritation at the back of the throat - Pharyngeal inflammation can occur but is not diagnostic of an STI.
Swollen neck glands with relevant exposure - Lymph-node enlargement can accompany many infections and needs appropriate clinical context.
A partner diagnosed with Gonorrhoea - Known exposure can justify testing even when the throat feels completely normal.
A partner diagnosed with Chlamydia - Site-specific screening may be indicated according to sexual contact.
Previous throat Gonorrhoea followed by new exposure - Previous infection does not provide immunity against reinfection.
Negative urine testing despite oral exposure - Separate throat testing is required because infection can be restricted to the pharynx.
A sore throat is far more commonly caused by viral or non-STI conditions than by Chlamydia or Gonorrhoea.
Difficulty swallowing, breathing difficulty, marked neck swelling, severe systemic illness or rapidly worsening throat symptoms require appropriate clinical assessment rather than relying solely on an STI PCR result.
How to Book Your Chlamydia/Gonorrhoea PCR (Throat Swab) Test
Booking a CT/NG throat PCR test with London Blood Tests is straightforward.
Choose the Chlamydia/Gonorrhoea PCR (Throat Swab)
Select the site-specific throat PCR test.
Select your sample collection option
Arrange an appropriate in-clinic or professional collection option for the required throat swab.
Attend your appointment
The throat specimen is collected using the laboratory-approved PCR swab from the appropriate pharyngeal area.
Laboratory analysis
Molecular analysis is performed for Chlamydia trachomatis and Neisseria gonorrhoeae genetic material.
Receive your results securely
Your authorised STI report is delivered confidentially, with clinical follow-up recommended when infection is detected.
When Will I Receive My Results?
The current London Blood Tests turnaround for the Chlamydia/Gonorrhoea PCR (Throat Swab) is approximately 1 business day after the specimen reaches the laboratory.
Your result is released once the molecular analysis and laboratory authorisation process are complete. Turnaround starts from laboratory receipt, so collection time, courier transport and weekends can affect the overall time from your appointment to receiving the report.
Occasionally, repeat analysis or a sample-quality issue can extend reporting. If Gonorrhoea is detected and culture or antimicrobial susceptibility testing is subsequently required, those tests are separate and take additional time.
Understanding Your Results
A not detected result means Chlamydia trachomatis and Neisseria gonorrhoeae genetic material was not identified in the throat specimen at the time of testing.
This makes pharyngeal infection less likely but should be interpreted according to the interval from exposure and whether antibiotics were taken before testing.
A Chlamydia detected result indicates molecular evidence of Chlamydia trachomatis at the pharyngeal site.
A Gonorrhoea detected result indicates Neisseria gonorrhoeae genetic material in the throat.
A positive result requires appropriate treatment and partner-management advice.
Because PCR does not determine antimicrobial susceptibility, additional Gonorrhoea culture may be clinically appropriate.
Following treatment, further testing may be recommended according to the infection site, treatment used and current sexual-health guidance.
The throat result applies only to the pharynx. It does not determine whether genital or rectal infection is also present.

Private Chlamydia/Gonorrhoea PCR (Throat Swab) Test in London
London Blood Tests provides private Chlamydia and Gonorrhoea throat PCR testing in London for people requiring confidential assessment following relevant oral sexual exposure.
The test costs £157.99 and contains one combined biomarker: Chlamydia/Gonorrhoea (Throat Swab).
Results are currently expected approximately 1 business day after laboratory receipt.
Because pharyngeal infection frequently produces no symptoms, the exposure site is often more important than symptoms when deciding whether throat testing is appropriate.
