In a healthy gut, there are healthy cell junctions and good nutrient absorption. In a leaky gut, however, the Villi are damaged, there is poor absorption and the cell junctions are loose. This means that bacteria and unwanted items can pass through the gut, as seen in the picture to the right.
Zonulin Testing can be performed with the patient’s first FIT 22 Test or FIT 132 Test to provide a baseline for the Zonulin levels. This gives patients the opportunity to track their progress after implementing an elimination diet based on the FIT Test results. We recommend retesting when you retest your FIT.
