Order Code LABMRSA Methicillin-Resistant Staphylococcus aureus (MRSA) by Molecular Detection, Nares 

Useful For

A qualitative screening test intended for the detection of methicillin-resistant Staphylococcus aureus (MRSA) DNA directly from nasal swabs in patients at risk for nasal colonization. 
Not intended to diagnose, guide, or monitor treatment for MRSA infections, or provide results of susceptibility to methicillin.

 

Limitations:

  • A detected test result does not necessarily indicate the presence of viable organisms. It is, however, presumptive for the presence of MRSA.
  • A not detected test result does not exclude the possibility of nasal colonization because test results may be affected by improper specimen collection, technical error, or because the number of organisms in the sample is below the limit of detection of the test
  • Assay interference may be observed in the presence of Nasonex (≥50% v/v), Flonase (≥50% v/v), and Beconase (≥40% v/v).
