The GI Health Panel can be incredibly valuable in the assessment of patients with abdominal distress. Due to the ease of administration and modest cost, the Regular and Expanded GI Health Panels might well be considered before other more cumbersome investigations.

GI Health Panel: Provider Overview

The Gastrointestinal Health Panel consists of stool and saliva testing:

Stool-Based Testing

The Regular and Expanded Gastrointestinal Panels include comprehensive testing of three stool samples to ensure the most accurate results. We screen for dysbiosis, GI pathogens, inflammatory markers, mucosal immunity, occult blood, and GI functional markers:

  • Culture for yeast
  • Microscopic ova and parasite study
  • Bacterial stool culture to identify pathogenic, opportunistic, and commensal organisms
  • Antigen and toxin assays for Shiga toxin, Campylobacter, Clostridium difficile, Giardia, and Cryptosporidium
  • Inflammatory biomarker levels – lysozyme, alpha 1-antichymotrypsin, and total intestinal sIgA – to detect significant irritation in the small or large intestine
  • Chymotrypsin measurement to aid in assessment of pancreatic function
  • Occult blood and fecal pH testing to further assess GI health and function

Saliva-Based Testing

In addition, the Diagnos-Techs GI Health Panels provide non-invasive, immune detection of specific parasites, bacteria, and food sensitivities via saliva markers including sIgA and IgG.
