IgG tests are explicitly not recommended by major allergy organizations such as the European Academy of Allergy and Clinical Immunology (EAACI) and the American Academy of Allergy, Asthma & Immunology (AAAAI), because they lead to false diagnoses and unnecessary dietary restrictions. The evidence is strong: numerous studies show that IgG levels correlate with tolerance, not allergy. Some labs market IgG tests for 'delayed' intolerances, but the scientific basis is lacking.
