GI-MAP + Zonulin

Research overwhelmingly indicates that gut health impacts overall health. The gut microbiome plays a critical role in mediating the effects of diet, digestion, immunity, metabolic function, and more. The GI-MAP (Microbial Assay Plus) test is truly unique in the field – relying exclusively on quantitative polymerase chain reaction (qPCR) technology to detect parasites, bacteria, fungi, and more by targeting the specific DNA of the organisms tested. The quantitative insights provided in this process, known for accuracy and reliability, allow practitioners to create more personalized treatment protocols for optimizing gut function and addressing dysfunction. This test includes a measurement of zonulin, a protein that modulates the permeability of tight junctions between cells of the wall of the digestive tract. It is used to help diagnose intestinal permeability/leaky gut.
