Test Code MPRP Mycoplasma (Mycoplasmoides) pneumoniae with Macrolide Resistance Reflex, Molecular Detection, PCR, Varies
Useful For
Diagnosing infections due to Mycoplasma (Mycoplasmoides) pneumoniae
Assessing macrolide susceptibility
Reporting Name
M pneumoniae PCR + Macrolide ReflexSpecimen Type
VariesNecessary Information
Specimen source is required.
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:
Specimen Type: Swab
Supplies:
-Culturette (BBL Culture Swab) (T092)
-BD E-Swab (T853)
-Nasopharyngeal Swab (Nylon Mini-Tip Swab) (T861)
-Culture Swab-Liquid Stuarts/Single Swab (NP Swab) (T515)
-M4-RT (T605)
Sources: Throat, nasal, or nasopharyngeal
Container/Tube:
Preferred: Culture swab transport system (Dacron or rayon swab with aluminum or plastic shaft with either Stuart or Amies liquid medium)
Acceptable: Culture transport swab (Stuart's media) or place swab in M4, M4-RT, M5, M6, universal transport media, or ESwab
Specimen Volume: Swab
Collection Instructions:
1. Collect specimen by swabbing back and forth over mucosa surface to maximize recovery of cells.
2. Place swab back into swab cylinder.

Reference Values
Negative
Interpretation
A positive result indicates the presence of Mycoplasma (Mycoplasmoides) pneumoniae. If detected, common mutations associated with macrolide resistance in M pneumoniae may be assessed.
A negative result does not rule out the presence of M pneumoniae and may be due to the presence of inhibitors within the specimen matrix or the presence of target DNA below the limit of detection of the assay.
