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:
Preserved Stool
Container/Tube:
Preferred: Stool container with 10% buffered formalin preservative (Supply T466)
Acceptable: SAF or MF
Specimen Volume: 5 g
Specimen Stability Information: Ambient (preferred)/Refrigerated
Unpreserved Stool
Container/Tube: Stool container (Supply T288)
Specimen Volume: 5 g
Collection Instructions: See Stool Collection Information Sheet in Special Instructions.
Specimen Stability Information: Frozen
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 g
Reject Due To Identifies specimen types and conditions that may cause the specimen to be rejected
