Experts Warn At-Home Food Intolerance Tests Are Misleading and Potentially Dangerous
A multimillion-pound industry promoting at-home food intolerance tests faces sharp criticism from medical experts who label the products as junk that should be banned. The article highlights a personal experiment comparing commercial home testing kits, including blood prick and bioresonance methods, against clinical-grade ALEX2 allergy tests. Despite the global allergy diagnostics market generating billions in revenue, there is absolutely no scientific evidence supporting the accuracy of most online intolerance tests, except for specific medical procedures like hydrogen breath tests for lactose intolerance or blood tests for coeliac disease. Experts warn that without professional clinical context, results are often misleading and can lead to unnecessary dietary restrictions or missed diagnoses. While IgE-mediated allergies can be detected via blood tests when interpreted alongside medical history, food intolerances generally do not involve the immune system in the same way, rendering many commercial tests useless. The piece underscores the risks consumers face when relying on unregulated diagnostic tools, emphasizing the distinction between clinically confirmed allergies and self-reported intolerances.
