Can COMT help with Haut?

As a scientific editor, I must state clearly: IgG-based food intolerance tests, as marketed by MyBody-X and similar providers, lack robust scientific support. IgG antibodies to foods are often a normal physiological response to dietary antigens and do not reliably indicate true intolerance or allergy. Major allergy guidelines (EAACI, AAAAI) explicitly recommend against using IgG panels for diagnosis, as they yield high false-positive rates and may lead to unnecessary dietary restrictions. The evidence level is marketing/unclear. If a patient presents such results, explain that the test cannot diagnose lactose intolerance, fructose malabsorption, or celiac disease. For persistent symptoms, validated methods like lactose hydrogen breath tests, supervised elimination diets, or specific IgE testing are appropriate. The risk of misinterpretation and nutritional deficiency from self-imposed diets is real. My advice: Do not base clinical decisions on these tests.
