The Intestinal Permeability Assessment is an effective and non-invasive assessment of small intestinal absorption and barrier function in the bowel. This test analyzes urine for the clearance of two non-metabolized sugars, lactulose and mannitol, identifying intestinal permeability (“leaky gut”) and poor absorption. Both poor absorption and increased leaky gut are associated with chronic gastrointestinal imbalances, as well as many general disorders.
