Mycoplasmoides genitalium Detection and Macrolide Resistance by PCR
Also known as: MACRO PCR
Use
This test is used to detect Mycoplasmoides (Mycoplasma) genitalium infection and predict resistance to macrolide antibiotics. Macrolide drug resistance is predicted based on melt probe analysis, focusing on common resistance-associated mutations at positions A2058, A2059, and A2062 of the 23S rRNA gene. The test is designed for clinical use to aid in the management of infections and antibiotic treatment decisions.
Special Instructions
The test is approved for use in New York state. Specimens must be in the form of genital swab, rectal swab, or urine. Viral transport media (ARUP supply #12884) is required for swabs or urine sample transport, which can be obtained via ARUP Connect™ or by contacting ARUP Client Services. Specimen source information is required when ordering the test.
Limitations
While the test predicts macrolide resistance by detecting known mutations, it does not account for all possible resistance mutations. Mutations of unknown significance may be detected, indicating the potential presence of macrolide resistance that was not accounted during development. A negative result cannot rule out the presence of PCR inhibitors or detect nucleic acid at concentrations below the assay's level of detection.
