What role does Leaky Gut Test play in gut health?

The role of a Leaky Gut Test in gut health is not well-established by current scientific evidence. These tests typically measure markers like zonulin or lipopolysaccharides (LPS) in blood or stool to assess intestinal permeability. However, the clinical validity of these markers is weak: studies show inconsistent results, and there are no standardized reference ranges. Many commercial tests are marketed with exaggerated claims, despite limited predictive value for individual health. A positive result does not necessarily indicate a treatable condition, as gut permeability can be influenced by diet, stress, medications, and other transient factors. Instead of relying on a single test, a comprehensive evaluation by a healthcare professional is recommended. Caveat: Do not self-diagnose or self-treat based on leaky gut tests; consult a gastroenterologist if you have persistent digestive symptoms.
