How are Leaky Gut Test and gut health related?

The relationship between a Leaky Gut Test and gut health is not clearly established in the scientific literature. These tests typically measure markers of intestinal permeability (e.g., zonulin, lactulose/mannitol ratio). Increased permeability is associated with conditions like IBS, IBD, and celiac disease, but commercial tests often lack standardized reference ranges and clinical validation. The provided context does not contain specific information about Leaky Gut Tests. Therefore, the evidence level is unclear/mechanistic. Caution is advised: a positive test result does not automatically indicate a need for specific dietary or therapeutic interventions without medical evaluation.
