Test ID: CDRP
Clostridium difficile Toxin, Molecular Detection, PCR
Specimen Type
Describes the specimen type needed for testing
Fecal
Specimen Required
Defines the optimal specimen. This field describes the type of specimen required to perform the test and the preferred volume to complete testing. The volume allows automated processing, fastest throughput and, when indicated, repeat or reflex testing.
Forms: If not ordering electronically, submit a Microbiology Request Form (Supply T244) with the specimen.
Submit only 1 of the following specimens:
Preferred:
Specimen Type: Preserved Stool
Container/Tube: Commercially available transport system specific for recovery of enteric pathogens from fecal specimens (15 mL of non-nutritive transport medium containing phenol red as a pH indicator, either Cary-Blair or Para-Pak C and S)
Specimen Volume: Representative portion of stool
Acceptable:
Specimen Type: Unpreserved Stool
Container/Tube: Stool container (Supply T288)
Specimen Volume: Representative portion of stool
Specimen Minimum Volume
Defines the amount of specimen required to perform an assay once, including instrument and container dead space. Submitting the minimum specimen volume makes it impossible to repeat the test or perform confirmatory or perform reflex testing. In some situations, a minimum specimen volume may result in a QNS (quantity not sufficient) result, requiring a second specimen to be collected.
1 mL
Reject Due To
Identifies specimen types and conditions that may cause the specimen to be rejected
