The Zonulin Family Protein - Stool test measures the levels of zonulin proteins in stool samples. Zonulin proteins play a key role in modulating intestinal permeability by regulating tight junctions between cells in the gut lining. This test helps assess gut barrier function and intestinal health by detecting changes that may indicate increased intestinal permeability. It is a non-invasive diagnostic tool designed to provide valuable insights into gastrointestinal conditions. The test is processed by Doctor's Data, a recognised leader in specialised laboratory testing.
