Mycoplasma genitalium, NAA, Urine With Reflex to Macrolide Resistance Testing
Use
The test is used to detect the presence of Mycoplasma genitalium in urine collections. If M. genitalium is detected, further testing for the presence of macrolide resistance will be performed.
Special Instructions
Reflex testing may incur additional charges or CPT code changes. It is crucial for patients to follow specimen collection instructions to ensure test sensitivity. Patients should not urinate for at least one hour before collection and should provide a first-catch urine sample. Female patients should avoid cleansing the labial area before collection.
Limitations
A negative result does not necessarily rule out the presence of Mycoplasma genitalium. Results can be affected by improper specimen collection, suboptimal target levels below the limit of detection, or erroneous interpretation without taking other clinical data into account. Proper specimen handling, including collection, transport, and storage, is essential to avoid incorrect outcomes.
