Result Turnaround Time
3 - 6 days
Turnaround time is defined as the usual number of days from the date of pickup of a specimen for testing to when the result is released to the ordering provider. In some cases, additional time should be allowed for additional confirmatory or additional reflex tests. Testing schedules may vary.
Use
Detect the presence of carbapenem-resistant or carbapenemase-producing Klebsiella spp and E coli from rectal specimens from patients in hospitals or long-term nursing care environments.
Special Instructions
This test is intended only for detection of carbapenem-resistant or carbapenemase-producing Klebsiella spp and E coli from rectal swabs. For culture and isolation of other potential pathogens, a stool culture (or other test appropriate for the specimen source) should be ordered.
Limitations
Patients may be colonized with CRE or carbapenemase-producing Enterobacteriaceae at a concentration that is not detectable by this method.
