Questions people ask about IgG Unverträglichkeit Kinder

IgG-based food intolerance tests for children are scientifically controversial. Measured IgG antibodies often reflect normal immune exposure rather than true intolerance. Studies show these tests frequently yield false positives, leading to unnecessary dietary restrictions that may risk malnutrition in children. The German Society for Allergology and Clinical Immunology (DGAKI) and other professional bodies advise against using IgG tests for diagnosing food intolerances. Instead, evidence-based approaches like supervised elimination diets or IgE allergy testing should be used when indicated. The evidence base is weak, relying mainly on mechanistic reasoning and marketing claims. For children with digestive issues, a pediatric evaluation is more important than any DNA or IgG test.
