Can COMT help with allergy?

The question whether COMT can help with allergies lacks solid scientific support. COMT (catechol-O-methyltransferase) primarily metabolizes catecholamines like dopamine and adrenaline, not histamine or other allergy mediators. Some research explores indirect links via stress and immune regulation, but evidence is weak and inconsistent. The provided context explicitly states that no validated genetic markers exist for allergies. Combined IgE/IgG tests are misleading: IgE is clinically valid for immediate-type allergies, while IgG is not evidence-based for food intolerance. Therefore, COMT genotyping is not useful for allergy management. Rely on validated IgE testing and clinical evaluation instead.
