What role does Leaky Gut Test play in Darmgesundheit?

The role of a 'Leaky Gut Test' in gut health is not addressed in the provided context. Leaky gut (increased intestinal permeability) is a debated concept: while some functional medicine practitioners and labs offer tests for zonulin, LPS, or gut barrier markers, these lack standardized, clinically validated protocols. Evidence for their utility in diagnosis or treatment guidance is weak, mostly mechanistic or from animal studies. Current gastroenterology guidelines do not recommend them. For established conditions like celiac disease or IBD, validated tests (tTG antibodies, endoscopy) exist. A commercial leaky gut test without medical supervision may lead to misinterpretation and unnecessary dietary restrictions. Evidence: mixed/unclear. Safety note: persistent GI symptoms warrant a physician's evaluation.
