A Mycoplasma genitalium (MG) urine test looks for genetic material from a common bacterium that can infect the urinary and genital tracts. It is usually ordered when someone has symptoms such as discharge, burning with urination, or pelvic discomfort, or after possible exposure. MG can also be present without symptoms.
What it measures
- Mycoplasma genitalium DNA — The test detects the bacterium's genetic material in urine, showing whether MG is present.
- Macrolide resistance markers — Some tests also check for changes in MG DNA linked to resistance to a common antibiotic class.
- Collection adequacy — Confirms the urine sample is suitable for testing, so results are reliable.
Who it is for
A healthcare clinician typically orders this test for people with urinary or genital symptoms, for sexual partners of someone with MG, or as part of screening in certain situations. It is not a routine test for everyone.
Preparation
No fasting is needed. For best results, collect urine at least one hour after last urinating, and follow any instructions from your clinician or lab about the collection method.
Results and what they mean
Results are usually reported as detected or not detected, sometimes with resistance information. A clinician interprets results alongside symptoms, history, and other tests. This is general information, not medical advice; discuss your results with a qualified clinician.

Frequently asked questions
How is the sample collected?
You provide a urine sample, often a first-catch sample, in a private collection area at the lab or clinic.
How long until results are ready?
Most results are available within 1 to 3 business days, though timing can vary by lab.
Can I have MG without symptoms?
Yes. Many people with MG have no symptoms, which is why testing may be recommended after exposure.
Should my partner be tested too?
A clinician can advise whether partners should be tested or treated, since MG can pass between people during sex.
