Additional Codes

Mayo test code: KNSRP

Reporting Name

KPC and NDM Surveillance PCR

Useful For

Performing Laboratory

Mayo Clinic Laboratories in Rochester

Specimen Type


Advisory Information

This assay should be used for surveillance testing on perirectal/rectal swabs or fecal specimens. If testing isolates from culture, order KPNRP / KPC (blaKPC) and NDM (blaNDM) in Gram-Negative Bacilli, Molecular Detection, PCR, Varies.

Necessary Information

Specimen source is required.

Specimen Required

The high sensitivity of amplification by PCR requires the specimen to be processed in an environment in which contamination of the specimen by KPC or NDM DNA is not likely.


Submit only 1 of the following specimens:



-Culturette (BBL Culture Swab) (T092)

-C and S Vial (T058)



Specimen Type: Perianal, perirectal, rectal

Collection Container/Tube: Culture transport swab (Dacron or rayon swab with aluminum or plastic shaft with either Stuart or Amies liquid medium)
