Highly accurate NAAT testing for chlamydia and gonorrhoea from a home urine or swab sample. Fast, discreet, and GMC-reviewed. Results in 3 to 5 working days.
Chlamydia and gonorrhoea are the two most commonly diagnosed bacterial sexually transmitted infections in England. Both are frequently asymptomatic — particularly chlamydia, where up to 70 percent of women and 50 percent of men report no symptoms — meaning they are easily transmitted unknowingly. If left untreated, both infections can cause serious complications including pelvic inflammatory disease, epididymo-orchitis, fallopian tube scarring, and infertility. Gonorrhoea is of increasing public health concern due to rising rates of antibiotic resistance. This test uses nucleic acid amplification testing (NAAT), the gold-standard method with sensitivity above 95 percent for both pathogens, from a home-collected urine or swab sample. Results are reviewed by a GMC-registered physician who provides clear treatment pathway guidance if either test is positive.

NAAT for chlamydia and gonorrhoea has a window period of approximately 1 to 2 weeks from the time of infection; testing earlier than 14 days post-exposure may produce a false negative result. Urine NAAT is highly accurate for urethral infection but is somewhat less sensitive for rectal and pharyngeal infection; if you have had anal or oral sexual contact with a potentially infected partner, rectal or throat swabs are more appropriate and should be requested through a sexual health clinic. A positive gonorrhoea result should be followed by culture and sensitivity testing at a sexual health clinic to guide antibiotic selection given the increasing prevalence of antibiotic resistance.

Contact supportNo. Chlamydia is often called the ‘silent infection’ because the majority of infected individuals have no symptoms at all. Studies suggest that up to 70 percent of women and 50 percent of men with chlamydia are asymptomatic. When symptoms do occur in women, they may include unusual vaginal discharge, pelvic pain, bleeding between periods, or pain during intercourse. In men, symptoms may include urethral discharge, burning on urination, or testicular discomfort. Because symptoms are so often absent, regular testing is the only reliable way to know your status.
Chlamydia is effectively treated with a short course of antibiotics. The most commonly used regimen is either a single dose of azithromycin (1 gram) or a seven-day course of doxycycline (100 mg twice daily). Current UK guidelines prefer doxycycline for non-pregnant adults due to slightly higher cure rates. Sexual partners from the preceding 6 months should be notified and tested. You should abstain from sexual contact for 7 days after completing treatment, or until all partners have also been treated, to avoid reinfection.
Neisseria gonorrhoeae has a remarkable ability to acquire antibiotic resistance through horizontal gene transfer and mutation. Over the past three decades, it has successively developed resistance to penicillin, tetracyclines, fluoroquinolones, and more recently some cephalosporins. The current recommended treatment in the UK is a single intramuscular injection of ceftriaxone, delivered in a sexual health clinic. Cases of extensively drug-resistant gonorrhoea that do not respond to ceftriaxone have been reported globally. This is why gonorrhoea must be treated at a sexual health clinic with culture and sensitivity testing rather than empirically at home, and why partner notification and follow-up confirmation of cure are essential.
In women, untreated chlamydia can ascend from the cervix to the upper reproductive tract, causing pelvic inflammatory disease (PID). PID can result in fallopian tube scarring, which is a leading cause of tubal factor infertility and ectopic pregnancy. It is estimated that approximately 10 to 15 percent of women with untreated chlamydia develop PID, and one episode of PID reduces fertility by approximately 10 to 12 percent. In men, chlamydia can cause epididymo-orchitis (inflammation of the epididymis and testicle) and, if chronic, contribute to male factor infertility. Both partners should be treated simultaneously to prevent reinfection.
Yes, and it is recommended. NHS guidelines suggest a test of cure approximately 5 to 6 weeks after completing antibiotic treatment for gonorrhoea to confirm eradication, given the antibiotic resistance concerns. For chlamydia, a test of cure is recommended in pregnant women and when compliance with the full antibiotic course is uncertain. If you have been treated and want to confirm cure before resuming sexual activity, retesting at least 5 weeks after completing treatment is advisable. Testing too early can produce a false positive due to residual DNA from dead bacteria.
