Test ID KPNDP Klebsiella pneumoniae Carbapenemase (blaKPC) and New Delhi Metallo-beta-Lactamase (blaNDM) Surveillance, PCR, Varies
Ordering Guidance
This assay should be used for surveillance testing on perirectal/rectal/perianal, anal swabs, or fecal specimens only. 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 polymerase chain reaction requires the specimen to be processed in an environment in which contamination of the specimen by Klebsiella pneumoniae carbapenemase or New Delhi metallo-beta-lactamase DNA is not likely.
Submit only 1 of the following specimens:
Preferred:
Specimen Type: Perianal, anal, perirectal, rectal
Supplies: Culturette (BBL Culture Swab) (T092)
Container/Tube: Culture transport swab (Dacron or rayon swab with aluminum or plastic shaft with either Stuart or Amies liquid medium)
Specimen Volume: Swab
Specimen Stability Information: Refrigerated (preferred)/Frozen
Acceptable:
Specimen Type: Preserved feces
Supplies: Culture and Sensitivity Stool Transport Vial (T058)
Container/Tube: Commercially available transport system specific for recovery of enteric pathogens from fecal specimens (15 mL of nonnutritive transport medium containing phenol red as a pH indicator, either Cary-Blair or Para-Pak C and S vial)
Specimen Volume: Representative portion of feces
Collection Instructions:
1. Collect fresh feces and submit 1 gram or 5 mL in container with transport medium.
2. Place feces in preservative within 2 hours of collection.
Specimen Stability Information: Ambient (preferred)/Refrigerated
