What role does IgG Unverträglichkeitstest play in Allergie?

IgG intolerance tests are often marketed to identify food intolerances or allergies, but the scientific evidence is weak. IgG antibodies to foods commonly reflect normal immune exposure, not an allergic or intolerant reaction. True food allergies are IgE-mediated and require clinical evaluation (e.g., skin prick test, oral challenge). IgG tests produce many false positives, leading to unnecessary dietary restrictions and potential nutrient deficiencies. Professional societies, including the European Academy of Allergy and Clinical Immunology (EAACI), advise against their use. For consumers: an IgG test cannot replace a doctor’s diagnosis for suspected allergy. The evidence is 'mixed/unclear' – no robust clinical trials demonstrate benefit. MyBody-X does not offer IgG tests; its focus is on validated biomarkers and DNA analysis with moderate evidence. Always consult a healthcare provider before making dietary changes based on such tests.
