What it measures
Mycoplasma genitalium is a sexually transmitted bacterium. The test looks for its genetic material in urine or a swab, using a nucleic acid amplification test (NAAT). Many people with it have no symptoms.
Why people test it
- Tested when discharge, pain passing urine or pelvic pain continue after other STI tests are negative.
- Checked when a sexual partner has been diagnosed with it.
- Part of wider sexual health screens.
Typical range
Reported as detected or not detected, and some labs also check for genetic signs of resistance to common antibiotics. Methods vary between labs, and your report shows how the lab reads the result.
Finger-prick or vein?
A urine sample or a swab, not blood. In wider sexual health panels it is sent alongside a blood sample for other infections.
