Typical costs related to IgG Unverträglichkeit Genetik

The question about typical costs for an IgG intolerance test with a genetic component requires careful clarification. First, IgG (immunoglobulin G) tests are widely marketed as food intolerance tests, but they are scientifically controversial. Major allergy and immunology societies (e.g., DGAKI, EAACI) advise against them because elevated IgG levels often reflect normal immune exposure to foods, not intolerance. True genetic tests (e.g., for lactose intolerance, celiac disease, or histamine intolerance) are more evidence-based. Costs: A standalone IgG blood test (covering 50–200 foods) typically ranges from €100 to €300, and is rarely reimbursed by health insurance. Genetic tests for single variants (e.g., LCT for lactose) cost about €30–€80. Combined IgG + genetic panels can cost €200–€500. However, limitations are significant: IgG tests do not diagnose intolerance, and genetic tests only indicate predisposition, not current symptoms. MyBody-X does not offer IgG tests; its focus is on microbiome, hormones, and DNA tests for longevity/nutrigenetics. Evidence for IgG testing is weak (marketing-driven), while genetic intolerance tests have moderate to strong evidence depending on the gene. Consumers should be wary of overpromising marketing and consult a doctor before spending on such tests.
