European Academy of Allergy and Clinical Immunology

Major professional allergy organizations have specifically recommended against using food-specific IgG or IgG4 testing to diagnose food allergy or intolerance.

The European Academy of Allergy and Clinical Immunology published a position paper concluding that IgG4 testing should not be used for the diagnosis of food-related adverse reactions The Canadian Society of Allergy and Clinical Immunology has also issued a formal position against food-specific IgG testing, noting that positive results are expected in healthy adults and children and can reflect exposure and tolerance rather than hypersensitivity.

And the American Academy of Allergy, Asthma, and Immunology advises against using IgG food testing to diagnose food intolerance or sensitivity.

That's an important consensus.
