The following bacteria, parasites, and viruses are identified using the GI Pathogen Profile:

Bacteria

• Campylocbacter (C. jejuni/C. upsaliensis)
• Clostridium difficile (toxin A/B)
• Pleasiomonas shigelloides
• Salmonella
• Vibrio (parahemolyticus, vulnificus, cholerae)
• Vibrio cholerae
• Yersinia enterocolitica

Viruses

• Adenovirus F 40/41
• Astrovirus
• Norovirus GI/GII
• Rotavirus A
• Sapovirus (I, II, IV, and V)

Diarrheagenic E. coli/Shigella

• E. coli O157
• Enteroaggregative E. coli (EAEC)
• Enteropathogenic E. coli (EPEC)
• Enterotoxigenic E. coli (ETEC) lt/st
• Shiga-like toxin-producing E. coli (STEC) stx1/stx2
• Shigella/Enteroinvasive E. coli (EIEC)

Parasites

• Cryptosporidium
• Cyclospora cayetanesis
• Entamoeba histolytica
• Giardia duodenalis (aka lamblia & intestinalis)

Sample Report

Using advanced PCR technology for genetic level testing*, this GI pathogen panel detects and identifies 22 of the most common and problematic gastrointestinal viruses, parasites and bacteria in order to expedite clinical options, especially for diarrheal illnesses.

While bacteria and parasites are the primary cause of food and water-borne diarrheal illness, the vast majority of acute diarrheal illness is caused by viral infections. In fact, Norovirus is the primary gastrointestinal infection occurring the in the US and the leading cause of foodborne illness.¹

This stool test can be used as a stand-alone or as an add-on to our Comprehensive Stool Analysis with Parasitology x1 (LC100083), to test for the presence of viral infections or to differential between possible diarrheagenic strains of E. Coli.

Instructions

The following documents provide a full set of instructions and the contents of the lab kit for completing the test:

Instructions      

Note

Results take 2-3 weeks from the time the laboratory receives your sample. This test is not available in Pennsylvania. The results for this test are not available online.

Special Note

Since coinfection of multiple organisms can occur, additional stool testing may be valuable to evaluate additional organisms causing symptoms and/or disease.

The CSA w/ Parasitology (LC100083) is the best choice for chronic issues of 3 months or longer. The GI Pathogen Profile is best choice for sudden changes in the GI tract, such as recent travel induced GI issues or consumption of questionable food from a new restaurant. For complicated ongoing or recurring issues, both tests can be done simultaneously to provide the maximum amount of information.

*Currently, validated FDA-cleared probes exist only for pathogenic species.
