Enteric Pathogens Culture, Stool

Testing Algorithm Delineates situation(s) when tests are added to the initial order. This includes reflex and additional tests.

When this test is ordered, the reflex tests may be performed and charged separately. Includes Aeromonas, Campylobacter, Salmonella, Shigella, and Yersinia.

Note: Does not include culture for Escherichia coli O157:H7.

 

See Laboratory Testing for Infectious Causes of Diarrhea in Special Instructions.

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.

Specimen must arrive within 96 hours of collection.

 

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 specimen

Collection Instructions: Collect fresh stool and submit 1 gram or 5 mL in container with transport medium.

Additional Information: If Vibrio is suspected, order VIBC / Vibrio Culture, 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.
