Test Code CARBAR Carbapenem Resistant Screen 

Important Note

Limited to Infection Prevention Requests

Useful For

This assay is performed on rectal and perirectal swab specimens from patients at risk of intestinal colonization with carbapenem-non-susceptible bacteria. Concomitant cultures are necessary to recover organisms for epidemiological typing, antimicrobial susceptibility testing, and for further confirmatory bacterial identification. The Xpert Carba-R Assay, when performed on rectal and perirectal swab specimns, is not intended to guide or monitor treatment for carbapenem-non-susceptible bacterial infections or to determine infection from carbapenem-non-susceptible bacteria.

Specimen

Rectal or perirectal swab:

Only dual copan swabs (Cepheid) are acceptable and are available through the Microbiology Laboratory. 

 

Collection of a paired rectal swab:

Carefully insert both swab tips approximately 1cm beyond the anal sphincter and rotate gently.

 

Specimen stability:

Swabs in the transport media can be stroed at 15-28°C for up to 5 days.
