Antimicrobial Susceptibility - Surveillance Carbapenemase Gene Detection by PCR
Also known as: CARBA SWAB
Use
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. It serves as an aid to infection control in detecting carbapenem-resistant bacteria. It's intended for use in infection control and is not suitable for guiding or monitoring infection treatment.
Special Instructions
Rectal swab specimens should be collected and transported in eSwab transport media. This testing is conducted in a CLIA certified laboratory, but it has not been cleared or approved by the FDA. For New York state, submit a Non-Permitted Laboratory Request Form to the NYDOH before specimen collection.
Limitations
The assay generates false-negative results for samples containing certain IMP gene sequences. It does not detect resistance mechanisms other than those conferred by the targeted gene families, and negativity can't exclude resistance mechanisms or low-concentration nucleic acids.
