Myths vs facts: Ferritin Eisenmangel and Allergie

The question about myths vs facts regarding ferritin, iron deficiency, and allergies is not addressed in the provided context. Therefore, an evidence-based answer is limited. Generally, ferritin is an iron-storage protein; low levels indicate iron deficiency. Some studies suggest a link between iron deficiency and increased allergy risk (e.g., via impaired immune regulation), but the evidence is mostly mechanistic and not supported by large clinical trials. Marketing claims that directly connect ferritin levels to allergies should be viewed critically. Iron deficiency should be diagnosed via complete blood count, ferritin, and transferrin saturation – not by a DNA test alone. For allergies, specific IgE tests or provocation tests are standard. Caveat: case reports or correlations do not replace clinical workup. The MyBody-X tests mentioned in the context (DNA, microbiome, celiac) do not provide direct information on this topic.
