What role does AllergieCheck | IgE-Antikörper Test play in gut health?

The AllergieCheck (IgE antibody test) measures specific IgE antibodies to food and environmental allergens. While elevated IgE can indicate an allergic response that may affect the gut (e.g., in food allergies causing gastrointestinal symptoms), the test does not assess gut health directly. It cannot diagnose gut microbiome composition, intestinal permeability, or inflammation. Many positive IgE results reflect sensitization without clinical allergy, leading to unnecessary dietary restrictions. The test is best used as a screening tool alongside medical evaluation, not as a standalone gut health assessment. Evidence: marketing/unclear. Sources: none provided in context.
