HelpTest ID VRERP Vancomycin-Resistant Enterococcus, Molecular Detection, PCR, Varies
Useful For
Identifying carriers of vancomycin-resistant enterococci
Highlights
This test detects the presence of either vanA or vanB, which confer vancomycin resistance in Enterococcus faecalis and Enterococcus faecium (and occasionally other organisms).
Method Name
Real-Time Polymerase Chain Reaction (PCR)
Reporting Name
VRE PCRSpecimen 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 vancomycin-resistant Enterococcus DNA is unlikely.
