Overview of the Mycoplasma genitalium by PCR Test
The Mycoplasma genitalium by PCR test detects genetic material from Mycoplasma genitalium, a sexually transmitted bacterium that can infect the urethra, cervix and other genital sites.
The test assesses 1 specialist biomarker: Mycoplasma genitalium by PCR.
Mycoplasma genitalium, often abbreviated to M. genitalium or Mgen, is a recognised sexually transmitted infection.
Many infections cause no obvious symptoms.
When symptoms occur, they can overlap with Chlamydia, Gonorrhoea and other genital infections.
In men, M. genitalium is an established cause of non-gonococcal urethritis and can produce burning during urination or urethral discharge.
In women, infection can involve the cervix and has been associated with pelvic inflammatory disease.
PCR testing is used because Mycoplasma genitalium is difficult and extremely slow to grow using routine bacterial culture.
The molecular assay detects bacterial nucleic acid directly from the submitted specimen.
Depending on the clinical situation, testing may use first-catch urine or an appropriate genital swab.
A positive result indicates that M. genitalium DNA has been detected.
Treatment requires care because antibiotic resistance, particularly macrolide resistance, is increasingly important.
Where available or clinically indicated, resistance testing can help guide treatment selection.
A negative result means M. genitalium was not detected in the specimen tested, although very early infection, recent antibiotic use or an unsuitable specimen can reduce detection.
The test does not automatically screen for other sexually transmitted infections unless they are ordered separately.
What Does the Mycoplasma genitalium by PCR Test Check?
The test uses PCR to detect Mycoplasma genitalium genetic material. This test measures 1 specialist biomarker.
Mycoplasma genitalium by PCR
Detects Mycoplasma genitalium DNA in an appropriate urine or swab specimen, supporting diagnosis of active infection.
Who May Benefit From the Mycoplasma genitalium by PCR Test?
Testing can be useful when symptoms persist, a partner has been diagnosed or targeted STI investigation is required.
People with persistent urethral symptoms - M. genitalium can cause non-gonococcal urethritis.
People with burning during urination - Dysuria can occur with genital infection.
People with unexplained urethral or genital discharge - PCR can identify M. genitalium as one possible cause.
Women with cervicitis or persistent genital symptoms - M. genitalium can infect the cervix.
People with persistent symptoms despite negative Chlamydia and Gonorrhoea tests - Targeted Mgen testing can identify an infection not included in some basic STI screens.
People whose sexual partner has tested positive for M. genitalium - Partner assessment and testing may be appropriate.
People with recurrent symptoms after previous treatment - Repeat testing or resistance assessment can sometimes be required.
People undergoing broader STI assessment - Mgen can be tested alongside other sexually transmitted infections.
How to Prepare
Do not take antibiotics solely to prepare for the test.
If a swab specimen rather than urine is clinically required, collection should follow the appropriate clinic protocol.
Symptoms and Reasons to Consider the Mycoplasma genitalium by PCR Test
Many M. genitalium infections are asymptomatic, but genital and urinary symptoms can occur.
Burning or discomfort when urinating - Urethral inflammation can cause dysuria.
Urethral discharge - Infection can produce discharge in men.
Unusual vaginal or cervical discharge - Cervical infection can cause changes in discharge.
Pelvic discomfort - M. genitalium has been associated with pelvic inflammatory disease.
Bleeding after sex - Cervical inflammation can occasionally contribute.
Persistent genital symptoms after negative routine STI testing - Mgen may not be included in all standard screens.
A sexual partner diagnosed with M. genitalium - Exposure increases the likelihood of infection.
Severe pelvic pain, fever, testicular pain or rapidly worsening symptoms require clinical assessment.
A positive result should be managed according to current sexual-health guidance because antimicrobial resistance can affect treatment choice.
How to Book Your Mycoplasma genitalium by PCR Test
The Mycoplasma genitalium PCR test can be booked privately for direct molecular detection of Mgen infection.

Select your sample collection option
The appropriate urine or site-specific specimen pathway is selected according to the clinical requirement; swab collection is performed in clinic where required.
Attend your appointment
Provide the requested urine specimen or have the appropriate swab collected.
Laboratory analysis
Your specimen undergoes PCR detection of Mycoplasma genitalium by PCR.
Receive your results securely
Your authorised result is delivered securely and resistance testing can be considered where appropriate.
When Will I Receive My Results?
The current London Blood Tests turnaround is approximately 2 days after laboratory receipt.
PCR processing includes nucleic-acid extraction, amplification, quality control and result authorisation.
Additional macrolide-resistance testing, if ordered, has a separate turnaround.
Understanding Your Results
A negative result means Mycoplasma genitalium DNA was not detected in the specimen.
This makes infection at the tested site less likely.
A positive result confirms that M. genitalium genetic material was detected.
Treatment should follow appropriate clinical guidance because resistance to commonly used antibiotics is an important issue with this infection.
A positive result does not show whether complications such as pelvic inflammatory disease are present.
Likewise, a negative test does not exclude other sexually transmitted infections.
Chlamydia, Gonorrhoea, Trichomonas and other pathogens may require separate testing depending on symptoms and exposure.
Why Book With London Blood Tests?
London Blood Tests provides private PCR testing for direct detection of Mycoplasma genitalium.
Uses molecular PCR testing - The test detects bacterial genetic material directly.
