What to watch with Leaky Gut Test and Allergie?

When considering a Leaky Gut Test and allergy tests, caution is warranted. The Leaky Gut Test (e.g., zonulin, LPS) is scientifically controversial – no standardized cutoffs exist, and clinical relevance is unclear. Many providers market it as an indicator of a 'leaky' gut barrier, but evidence is weak (mechanistic, lacking large human studies). For allergy tests: clearly distinguish between IgE-mediated immediate allergies (robust, e.g., skin prick test, specific IgE) and IgG tests for food intolerances. The latter are often marketed as 'allergy tests' but are not recommended by guidelines – IgG merely reflects exposure, not allergy. Combining both risks misinterpretation and unnecessary dietary restrictions. My advice: If you suspect real allergies or gut issues, seek medical evaluation, not self-diagnosis via home tests. MyBody-X DNA tests show genetic predispositions, not acute conditions. Evidence: mixed/marketing.
