HelpTest Code RPMPM Mycoplasma (Mycoplasmoides) pneumoniae Macrolide (Azithromycin) Resistance Prediction, Molecular Detection, PCR, Varies
Additional Codes
Torrance Memorial Laboratories Test Code: 5466654887
Ordering Guidance
This test should only be ordered on specimens that have tested positive for Mycoplasma (Mycoplasmoides) pneumoniae. This assay predicts M pneumoniae macrolide (Azithromycin) resistance only.
For detection of M pneumoniae prior to macrolide resistance testing , order MPRP / Mycoplasma (Mycoplasmoides) pneumoniae with Macrolide Resistance Reflex, Molecular Detection, PCR, Varies.
Necessary Information
Specimen source is required; include the specific anatomic source.
Specimen Required
The high sensitivity of amplification by polymerase chain reaction requires the specimen to be processed in an environment in which contamination of the specimen by Mycoplasma (Mycoplasmoides) pneumoniae DNA is unlikely.
Submit only 1 of the following specimens:
