Is AllergieCheck | IgE-Antikörper Test useful for Darmgesundheit?

The AllergieCheck (IgE antibody test) from MyBody-X measures specific IgE antibodies against food and environmental allergens. It is designed for detecting type I (immediate) allergies, not for assessing gut health. Impaired gut barrier or food intolerances (e.g., lactose intolerance, celiac disease) are not captured by IgE tests. While untreated allergies can indirectly affect gut function, the test provides no direct information on microbiome, inflammation markers, or digestive performance. For comprehensive gut diagnostics, stool analyses (microbiome, calprotectin, elastase) or specific IgG tests (controversial) would be more appropriate. The evidence for the IgE test's usefulness in gut health is weak and based on marketing claims. Consult a gastroenterologist if you suspect gut issues.
