Carbapenemase Confirmation

Message

LAB REFLEX TEST ONLY:  Susceptibility and/or drug resistance work up.




Test Code
$CROP


Alias/See Also
CARBA-R, XPERT Carba-R, CRO


CPT Codes
87150

Preferred Specimen
Colonies from cultures:  Enterobacteriaceae, Pseudomonas aeruginosa, Acinetobacter baumannii
Resistance genes evaluated:  IMP, OXA-48, VIM, NDM, KPC


Reference Range
Referenece Range:  Negative
  •  PCR testing indicated carbapenem resistance is not due to carbapenemase activity.  This information is used for epidemiology purposes.              
"POSITIVE" Results
  • This organism is a Carbapenem Resistant Enterobacteriaceae (CRE)..  Resistance gene present:  (IMP, OXA-48, VIM, NDM. KPC)


Clinical Significance
The Xpert® Carba-R Assay, performed on the GeneXpert® Instrument Systems, is a qualitative in vitro diagnostic test designed for the detection and differentiation of the blaKPC, blaNDM, blaVIM, blaOXA-48, andblaIMP gene sequences associated with carbapenem-non-susceptibility. The test utilizes automated real-time polymerase chain reaction (PCR).
