About this treatment

Gut health testing evaluates the function and integrity of your digestive system through specialized markers. Tests may measure intestinal permeability (zonulin), small intestinal bacterial overgrowth (SIBO breath testing), food intolerances, parasitic infections, or microbiome composition. The gut is increasingly recognized as central to overall health — influencing immune function, mental health, nutrient absorption, and systemic inflammation.

Results guide targeted interventions including dietary modifications, antimicrobial protocols, probiotics, and gut-healing supplements. Many chronic health issues — from skin conditions to autoimmune disease — have roots in gut dysfunction.

Who is this for?

People with chronic digestive symptoms (bloating, gas, irregular bowel movements). Those with unexplained fatigue, skin issues, or autoimmune conditions. Anyone interested in optimizing gut health for overall wellness. People who have traveled to areas with endemic parasites.

Preparation required

Follow test-specific instructions carefully — some require dietary preparation or fasting. Breath tests typically require a preparatory diet the day before. Stool tests have specific collection instructions. Bring a list of current supplements and probiotics.

Biomarkers tested

4
Hydrogen increase over baseline by 90 mins ppm

Bacteria in the small intestine produce hydrogen and methane when exposed to glucose. SIBO may be diagnosed with a rise in breath hydrogen of >20ppm in the first 90 minutes.

Peak hydrogen increase over baseline ppm

Amount of hydrogen in exhaled breath after lactose ingestion; indicates carbohydrate fermentation in the gut.

Peak methane increase over baseline ppm

Amount of methane in exhaled breath after lactose ingestion; indicates carbohydrate fermentation in the gut.

Peak methane level at any point ppm

Bacteria in the small intestine produce hydrogen and methane gas when exposed to lactulose. Methane excretion is indicated by >10ppm sustained rise upon lactulose challenge.
