Hydrogen/methane breath test to diagnose lactose malabsorption.
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.
Key Details
