How are IgG Unverträglichkeitstest and Darmgesundheit related?

IgG food sensitivity tests are often marketed as tools to assess gut health, but this relationship lacks scientific support. IgG antibodies to foods are a normal physiological response and do not indicate food intolerance or intestinal barrier dysfunction. Medical guidelines explicitly advise against using IgG tests for diagnosing food sensitivities or gut health issues. Reliable assessment of gut health involves stool microbiome analysis, calprotectin, or other validated markers. MyBody-X offers microbiome stool tests for gut health evaluation, but not IgE food allergy panels. Claims linking IgG tests to 'leaky gut' or overall gut health are not evidence-based. Consumers should be cautious: IgG results may lead to unnecessary dietary restrictions without clinical benefit. For genuine gut symptoms, consult a gastroenterologist and use evidence-based diagnostics.
