Can Eisen-Ferritin Selbsttest help with allergy?

The iron-ferritin self-test measures iron and ferritin levels in the blood, which are relevant for erythropoiesis and iron metabolism. There is no scientifically established link between these markers and allergies. Allergies are mediated by IgE antibodies, histamine release, and immune reactions to allergens – not by iron deficiency or overload. Therefore, an iron-ferritin test cannot diagnose allergies or explain their symptoms. MyBody-X's AllergieCheck (IgE test) is also not a diagnostic device but a lifestyle test. For allergy evaluation, an allergist with history, skin tests, and possibly provocation tests is required. The iron-ferritin test serves other purposes (e.g., iron deficiency). Claims that it helps with allergies are marketing-driven and not evidence-based. Caveat: isolated reports of iron deficiency and histamine intolerance are insufficiently substantiated.
