Test ID: CDFRP    
Clostridium difficile Toxin, Molecular Detection, PCR, Feces

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.

This test is validated for formed stool, although testing formed stool for Clostridium difficile is generally not clinically indicated.

 

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.
