Gastrointestinal Health Panel

The Gastrointestinal Health Panels (GI-1 and GI-02) include 15-22 separate screening tests to measure overall GI health and function. Stool and saliva samples are submitted by the patient after home collection.

Stool-Based Testing

The Regular (GI-1) and Expanded (GI-02) Gastrointestinal Health Panels include comprehensive testing of three stool samples to ensure the most accurate results. We evaluate 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.

Regular GI Health Panel includes:

  • Infectious (stool) – culture for yeast, bacterial stool culture, microscopic examination (ova and parasites), antigen and toxin assays (Shiga toxin, Campylobacter, Clostridium difficile, Giardia lamblia, and Cryptosporidium)
  • Immunologic and inflammatory (stool) – total intestinal sIgA, inflammatory markers (lysozyme, alpha 1-antichymotrypsin)
  • Infectious and immunologic (saliva) – Entamoeba histolytica antibody, sIgA; Helicobacter pylori antibody, IgG; Gluten (gliadin) antibody, sIgA
  • Other (stool) – chymotrypsin, occult blood, and fecal pH

Expanded GI Health Panel includes all GI-1 tests plus:

  • All tests included in the GI-1 panel (above)
  • Infectious (saliva) - Toxoplasma gondii antibody, sIgA; Taenia solium (tapeworm) antibody, sIgA; Ascaris lumbricoides (roundworm) antibody, sIgA; Trichinella spiralis antibody, sIgA
  • Immunologic (saliva) - milk (casein) antibody, sIgA; egg (ovalbumin) antibody, sIgA; and soy (protein) antibody, sIgA
