Eisen-Ferritin Selbsttest: what can you do yourself?

An iron/ferritin self-test measures ferritin levels in the blood, reflecting iron stores. What you can do yourself: perform the test at home (e.g., via dried blood spot) and obtain your ferritin value. If within the reference range, iron stores are likely adequate. If low, you could increase dietary iron (red meat, legumes, spinach) and enhance absorption with vitamin C. However, ferritin is an acute-phase reactant: inflammation, infection, or chronic disease can elevate it even when iron is deficient. A self-test alone does not replace medical evaluation. Without a full iron panel (serum iron, transferrin, transferrin saturation) and clinical interpretation, you risk misjudgment. Uncontrolled iron supplementation can be harmful in conditions like hemochromatosis or inflammation. Therefore, use the test as a preliminary screen, but consult a doctor for definitive diagnosis and management. Evidence: home test accuracy varies; self-directed action is of limited value without professional guidance.
