Test ID OVSRP Oxacillin-Hydrolyzing Beta-Lactamase (blaOXA-48-like) and Verona Integron-Encoded Metallo-Beta-Lactamase (blaVIM) DNA Surveillance, PCR, Varies

Useful For

Identifying carriers of Ggram-negative bacilli harboring oxacillin-hydrolyzing beta-lactamase (OXA-48-like) or Verona integron-encoded metallo-beta-lactamase (VIM) genes

Method Name

Real-Time Polymerase Chain Reaction (PCR) using LightCycler and Fluorescent Resonance Energy Transfer (FRET)

Reporting Name

OXA-48 and VIM Surveillance PCR

Specimen Type

Varies


Ordering Guidance


This assay is for surveillance testing on perirectal/rectal/perianal/anal swabs or fecal specimens only. If testing isolates from culture, request OXVRP / Oxacillin-Hydrolyzing Beta-Lactamase (blaOXA-48-like) and Verona integron-encoded metallo-beta-lactamase (blaVIM) in Gram-Negative Bacilli, Molecular Detection, PCR, Varies.

 

Other mechanisms of carbapenem resistance, including other carbapenemase-types, porin mutations, or hyper-expression of drug efflux pumps may result in carbapenem resistance. These are not detected by this assay. If testing for Klebsiella pneumoniae carbapenemase (KPC) or New Delhi metallo-beta-lactamase (NDM) is desired, order KNSRP / Klebsiella pneumoniae Carbapenemase (blaKPC) and New Delhi Metallo-beta-lactamase (blaNDM) Surveillance, PCR, Varies.



Additional Testing Requirements


If testing for Klebsiella pneumoniae carbapenemase (KPC) or New Delhi metallo-beta-lactamase (NDM) is also needed; also order KNSRP / Klebsiella pneumoniae Carbapenemase (blaKPC) and New Delhi Metallo-beta-lactamase (blaNDM) Surveillance, PCR, Varies.



Necessary 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 oxacillin-hydrolyzing beta-lactamase (blaOXA-48-like) or Verona integron-encoded metallo-beta-lactamase (blaVIM) DNA is unlikely.
