What to watch with Eisen-Ferritin Selbsttest and allergy?

The iron-ferritin self-test measures your iron stores (ferritin). Low ferritin may indicate iron deficiency, causing fatigue and poor concentration. Allergies are immune responses to triggers like pollen or food. There is no direct scientific link between ferritin levels and allergies. However, chronic iron deficiency can impair immune function, potentially influencing allergic responses – but this is not well-established. Be aware of test limitations: ferritin is an acute-phase protein that can rise during inflammation (including allergic reactions), masking true iron deficiency. Confirm abnormal results with a doctor. Allergy testing (e.g., IgE) is separate and not included in the ferritin test. Evidence: unclear, as no specific studies are provided in the context.
