The FIT Test is the most sensitive food test available using patented technology. The multiple pathway approach allows us to measure the whole immune system and looks at not only food sensitivities but also inflammation and gut permeability all from one test. We also provide best in class compliance tools including a personalized meal plan and a patient app to support. Measuring these multiple pathways enables us to eliminate false positive results commonly associated with IgG only food sensitivity testing.

Benefit Of Removing Food Sensitivities

Food sensitivity panels are helpful tools in identifying hidden food sensitivities and leaky gut contributing to adverse reactions and unwanted symptoms. Shared symptoms of food sensitivities and leaky gut syndrome include fatigue, changes in bowel movements, abdominal pain, skin rashes, and headaches. KBMO offers three FIT panels, leaky gut screening, and zonulin antibody measurement to accurately identify food sensitivities, intestinal permeability, and associated inflammation. Treatment plans can yield better patient results using FIT panels to guide elimination diets and gut-healing protocols.
