HelpOrderable Name CRPCR Carbapenem Resistance Genes, Molecular Detection, PCR, Rectal Swab
Ordering Guidance
This test is performed on rectal and perirectal swab specimens from patients at risk for intestinal colonization with bacteria not susceptible to carbapenem antimicrobials.
Other mechanisms of carbapenem resistance, including carbapenemases not targeted by this assay, porin mutations, and hyperexpression of drug efflux pumps, may result in carbapenem resistance. These mechanisms are not detected by this assay.
Specimen Required
Specimen Type: Rectal/perirectal swab
Supplies: Culturette (BBL Culture Swab) (T092)
Container/Tube: Culture transport swab
Specimen Volume: Entire collection
Useful For
Detecting and differentiating the blaKPC, blaNDM, blaVIM, blaOXA-48, and blaIMP gene sequences associated with carbapenem intermediate or resistant results
Aiding in infection control in the detection of gastrointestinal colonization of patients in healthcare settings with bacteria not susceptible to carbapenems using rectal or perirectal swabs
