Can Leaky Gut Test help with Allergie?

A Leaky Gut test measures intestinal permeability, often via markers like zonulin. Allergies are complex immune responses influenced by genetics, environment, and diet. There is no strong evidence that a Leaky Gut test can diagnose or guide allergy treatment. Most studies are small or mechanistic. MyBody-X may offer such a test, but its clinical validity for allergies is unclear. Caveat: consumer tests often overstate benefits; for suspected allergies, consult an allergist.
