Ordering Recommendation

Detect the presence of predominant carbapenemase genes (blaKPC, blaNDM, blaVIM, blaOXA-48, blaIMP) responsible for resistance to carbapenem and other beta-lactam antibiotics.

Mnemonic

CARBAR PCR

Methodology

Qualitative Polymerase Chain Reaction

Performed

Sun-Sat

Reported

1-2 days

New York DOH Approval Status

This test is New York DOH approved.

Specimen Required

Patient Preparation
Collect

Actively growing Enterobacteriaceae, Pseudomonas aeruginosa, or Acinetobacter baumannii in pure culture.

Specimen Preparation

Transport sealed container with pure culture on agar slant/bacterial transport media. Place each specimen in an individually sealed bag.

Storage/Transport Temperature

Room temperature.

Unacceptable Conditions

Mixed cultures or nonviable organisms.

Remarks

Isolate identification (for cultures) and specimen source required.

Stability

Ambient: 1 week; Refrigerated: 1 week; Frozen: Unacceptable

Reference Interval

Not Detected

Interpretive Data

This assay detects five carbapenemase gene families (blaKPC, blaNDM, blaOXA-48, blaVIM, blaIMP) encoding enzymes that may confer resistance to carbapenem and other beta-lactam antibiotics. This assay is intended for use as an aid to infection control in the detection of carbapenem-resistant bacteria and is not intended to guide or monitor treatment of infection. A negative result does not exclude the presence of other resistance mechanisms or assay-specific nucleic acid in concentrations below the level of detection.

Compliance Category

FDA

Note

An additional processing fee will be billed for all isolates not submitted in pure culture, as indicated in the specimen requirements.

If species identification is not provided, identification will be performed at ARUP. Additional charges apply.

This assay will generate a negative IMP result when testing samples containing IMP-7, IMP-13 or IMP-14 gene sequences, and may detect IMP-4 at reduced sensitivity.
