Antimicrobial Susceptibility - Carbapenemase Production
Use
This test is used to determine the production of carbapenem-inactivating enzymes in Gram-negative bacterial organisms, which is a common mechanism of carbapenem resistance. Detection of such enzymes aids in guiding treatment strategies for infections caused by carbapenemase-producing organisms. It's essential for infectious disease management and antibiotic stewardship.
Special Instructions
An additional processing fee will be billed for all organisms not submitted in pure culture, as indicated in the specimen requirements. If species identification is not provided, identification will be performed at ARUP, with additional charges applying. Isolate identification and specimen source are required prior to transport.
Limitations
The test is designed to assess carbapenemase production in pure cultures of Enterobacteriaceae species or Pseudomonas aeruginosa. Mixed cultures or non-viable organisms are unacceptable, and the test cannot be performed under those conditions. Furthermore, the test is not FDA-cleared or approved, indicating that it was developed and its performance characteristics determined by ARUP for clinical purposes only.
