The Mycoplasma genitalium (Mgen) Resistance Test from Repose Healthcare is a private, accurate test designed to detect the presence of Mycoplasma genitalium, a sexually transmitted infection (STI), and determine whether the infection carries genetic resistance to macrolide antibiotics (e.g., azithromycin).
Mycoplasma genitalium can cause urethritis, cervicitis, pelvic inflammatory disease (PID), and infertility if left untreated. Because antibiotic resistance is common, resistance testing helps clinicians select the most effective treatment and avoid failed antibiotic therapy.
Mycoplasma genitalium is a tiny bacterium that infects the urinary and genital tract. It is transmitted through unprotected vaginal, anal, or oral sex.
Infections are often asymptomatic, which means many people do not know they are infected. When symptoms do occur, they can include:
Painful urination (dysuria)
Urethral discharge in men
Vaginal discharge or pelvic pain in women
Post-coital bleeding
Pain during sex
Lower abdominal pain
Because Mgen can mimic other infections (such as chlamydia or gonorrhoea), accurate testing is essential.
Mycoplasma genitalium has high rates of resistance to macrolides (first-line antibiotics). Using the wrong antibiotic can:
Prolong infection
Worsen symptoms
Increase the risk of complications like PID and infertility
Promote further antibiotic resistance
Our test not only detects Mgen but also checks for mutations in the 23S rRNA gene, which are associated with resistance to macrolides. This ensures your healthcare provider can choose the most appropriate treatment from the start.
You may benefit from a Mycoplasma genitalium resistance test if you:
Have persistent or recurrent urethritis or cervicitis despite treatment
Have symptoms such as painful urination, discharge, or pelvic pain
Have a partner who tested positive for Mgen
Are experiencing treatment failure after taking azithromycin
Have been diagnosed with PID or unexplained infertility
Want to rule out Mgen as part of a comprehensive STI screen
Repose Healthcare offers testing using:
Urine sample – suitable for men and women
Vaginal swab – suitable for women and often preferred for higher sensitivity
Both sample types are analysed in UKAS-accredited laboratories for accurate results.
Order online – discreet packaging and delivery
Collect your sample – urine or vaginal swab kit with full instructions
Return to the lab – prepaid return envelope included
Get results online – private, secure results and explanation in just a few days
Your report will include:
Positive / Negative for Mycoplasma genitalium
Resistance profile – indicates whether macrolide resistance mutations are present
This information allows your clinician to prescribe the most effective antibiotic regimen, reducing the risk of treatment failure.
If untreated, Mgen can lead to:
Pelvic inflammatory disease (PID)
Tubal infertility
Chronic pelvic pain
Epididymitis (in men)
Increased risk of HIV transmission
Early detection and targeted treatment are crucial to prevent these complications.

1. What is a Mycoplasma genitalium resistance test?
The Mycoplasma genitalium resistance test detects the presence of the infection and identifies genetic resistance to macrolide antibiotics, helping your clinician select the most effective treatment.
2. How is Mycoplasma genitalium transmitted?
Mgen is a sexually transmitted bacterium, spread through unprotected vaginal, anal, or oral sex.
3. What are the symptoms of Mycoplasma genitalium?
Symptoms can include painful urination, urethral discharge in men, vaginal discharge, pelvic pain, post-coital bleeding, and discomfort during sex. Many infections are asymptomatic.
4. How do I take the test at home?
You can use a urine sample (men and women) or a vaginal swab (women). Follow the kit instructions, then return your sample using the prepaid envelope to a UK-accredited laboratory.
5. How long does it take to get results?
Results are usually available within 2–5 working days after the laboratory receives your sample, accessible securely online.
6. Who should take this test?
The test is recommended for individuals with persistent urethritis, cervicitis, pelvic pain, partners of someone who tested positive, or anyone wanting to check for macrolide-resistant Mgen.
7. Why is resistance testing important?
Mgen often shows resistance to macrolide antibiotics like azithromycin. Resistance testing ensures the correct antibiotic is prescribed, reducing treatment failure and preventing complications.
8. Is the test private and confidential?
Yes. The kit is delivered discreetly, and results are provided securely online to ensure full confidentiality.
9. Can I test for Mgen without symptoms?
Yes. Many people are asymptomatic, and testing can be part of routine sexual health screening or after potential exposure.
10. What complications can arise if Mgen is untreated?
Untreated infections can lead to pelvic inflammatory disease (PID), epididymitis, chronic pelvic pain, infertility, and increased risk of other STIs.
11. Can this test detect co-infections?
This test specifically detects Mycoplasma genitalium and its antibiotic resistance. For other STIs, separate tests like chlamydia, gonorrhoea, or trichomonas may be required.
12. Can I test during pregnancy?
Testing is generally safe during pregnancy, but consult your healthcare provider if you are pregnant or planning a pregnancy to discuss appropriate screening and treatment options.
