Common mistakes around IgG Unverträglichkeit Check

Common mistakes around IgG intolerance tests: Many people mistakenly believe that elevated IgG levels indicate a food intolerance. In reality, IgG antibodies against foods are a normal part of the immune system and typically only reflect exposure, not intolerance. Scientific guidelines (e.g., from the European Academy of Allergy and Clinical Immunology) advise against such tests because they cannot distinguish between tolerance and intolerance. Another mistake is implementing a strict elimination diet based on these results, which can lead to malnutrition and unnecessary restrictions. Marketing these as 'allergy tests' is misleading, as true allergies are mediated by IgE. The test does not provide a diagnosis but merely a list of foods often without clinical relevance. If a genuine intolerance is suspected (e.g., lactose intolerance, fructose malabsorption), validated methods like breath tests or medically supervised elimination diets are appropriate. MyBody-X does not offer IgG tests due to weak evidence.
