Test Code GI Panel Gastrointestinal Panel

Important Note

Clostridioides difficile (CDIFF) is NOT included in this panel.  A separate request for CDIFF is necessary if testing is required.

The Gastrointestinal Panel will replace the following tests currently performed in our laboratory: Stool Culture, Ova and Parasite Screening, Rotavirus and Norovirus. These tests will no longer be available as stand-alone orderable tests. They are included in the GI Panel and will provide faster turn-around time with greater sensitivity.

This test is not recommended as a test of cure.

Ordering Guidance

To aid in the diagnosis of specific agents of gastroenteritis. The following organisms are detected using the BioFire Gastrointestinal Panel.

-Campylobacter species (Campylobacter jejuni/Campylobacter coli/Campylobacter upsaliensis)

-Plesiomonas shigelloides

-Salmonella species

-Vibrio species (Vibrio parahaemolyticus, Vibrio vulnificus, Vibrio cholerae)

-Vibrio cholerae

-Yersinia species

-Enteroaggregative Escherichia coli (EAEC)

-Enteropathogenic E coli (EPEC)

-Enterotoxigenic E coli (ETEC)

-Shiga toxin

-E coli O157

-Shigella/Enteroinvasive E coli (EIEC)

-Cryptosporidium species

-Cyclospora cayetanensis

-Entamoeba histolytica

-Giardia

-Adenovirus F 40/41

-Astrovirus

-Norovirus GI/GII

-Rotavirus A

-Sapovirus

Specimen Collection

Feces

Collect specimen in Beebe provided stool specimen collection kit (plain container and orange capped Cary Blair Transport Media).

Specimen Minimum Volume

1 mL

Specimen Stability

Specimens preserved in Cary Blair Transport Medium are stable for 4 days at room temperature or refrigerated.

Reference Value

Negative / Not Detected.

 

If the folowing targets are detected, a stool culture will automatically be reflexed in order to perform antimicrobial susceptibility testing  when appropriate:

Campylobacter species

Plesiomonas shigelloides

Salmonella

Vibrio species

Vibrio cholerae

Yersinia enterocolitica

Interpretation

A negative result should not rule-out infection in patients with a high pretest probability for gastrointestinal infection. The assay does not test for all potential infectious agents of diarrheal disease.

 

Positive results do not distinguish between a viable or replicating organism and the presence of a nonviable organism or nucleic acid, nor do they exclude the potential for coinfection by organisms not contained within the panel.

 

Results of the panel are intended to aid in the diagnosis of illness and are meant to be used in conjunction with other clinical and epidemiological findings.
