Value of GI Health Panel: 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 GI-2 health panel might well be considered first before other more cumbersome investigations.

Gastrointestinal Health Panel: Provider Overview

The Gastrointestinal Health Panel consists of various types of testing:


  • Infectious (stool) - bacterial and fungal cultures, microscopic examination (ova and parasites), antigen assay (Giardia, Cryptosporidium)
  • Immunologic and inflammatory (stool) - total sIgA, inflammatory markers (lysozyme, alpha anti-chymotrypsin)
  • Infectious and immunologic (saliva) - H. pylori, gluten (gliadin) antibodies, sIgA
  • Other (stool) - chymotrypsin, occult blood, fecal pH


  • All regular tests included in the GI-1 panel
  • Infectious (saliva) - Toxoplasma gondii Ab (sIgA), Taenia solium Ab (sIgA), Ascaris Ab (sIgA), Trichinella Ab (sIgA)
  • Immunologic (saliva) - milk (casein) Ab (sIgA), egg (ovalbumin) Ab (sIgA), and soy protein Ab (sIgA)

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 pathogens, inflammatory markers, occult blood, and functional markers:
  • Culture for yeast and fungi to screen for fungal dysbiosis
  • Microscopic ova and parasite check
  • Culture for bacteria and flora to identify pathogenic and commensal organisms
  • Antigen testing for Giardia, Cryptosporidium, and Clostridium difficile
  • Inflammatory biomarker levels (lysozyme, alpha anti-chymotrypsin, intestinal sIgA) to detect significant irritation of 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
