Diagnostic Solutions Laboratory's Zonulin Profile is a diagnostic test that measures the level of zonulin in the body. Zonulin is a protein that regulates the permeability of the tight junctions between cells in the digestive tract. It controls the flow of molecules, including nutrients and antigens, between the bloodstream and the intestinal lumen.
Zonulin has emerged as a popular serological marker to assess the integrity of the intestinal mucosal barrier. Elevated levels of zonulin have been associated with autoimmune diseases, such as celiac disease.
