The GI Effects Comprehensive Stool Profile is a group of advanced stool tests that provide actionable clinical information for the management of gastrointestinal health. This profile offers insight into digestive function, intestinal inflammation, and the intestinal microbiome.
The Small Intestinal Bacteria Overgrowth (SIBO) profiles are non-invasive breath tests which capture exhaled hydrogen (H2) and methane (CH4) gases following patient ingestion of a lactulose solution to evaluate bacterial overgrowth of the small intestine.
Healthcare providers can access our full test menu when ordering through their myGDX account.
