Introducing Stool and Serum Zonulin

We are excited to announce the offering of stool and serum Zonulin as an Add-On to the following profiles:


Zonulin is a protein modulator of intestinal tight junctions that is used to assess intestinal permeability (IP). Recent peer-reviewed literature highlights the role that intestinal permeability plays in a host of chronic GI and systemic conditions. Patients who may benefit from Zonulin assessment include those with:

  • Leaky Gut Symptoms (bloating, gas, cramps, food sensitivities, joint pains, skin rashes and autoimmunity)
  • Celiac Disease and Gluten Sensitivity
  • GI Disorders (IBS)
  • Cardiometabolic Diseases (type 1 diabetes, type 2 diabetes, obesity, non-alcoholic fatty liver disease, and insulin resistance)

Please Note: Zonulin results will be reported on the last page of the test report.
