What to watch with Eisen-Ferritin Selbsttest and Haut?

The iron-ferritin self-test provides a snapshot of your iron status, but interpreting it for skin health requires caution. Low ferritin may indicate iron deficiency, which can manifest as pallor, brittle nails, or hair loss; less commonly, it may cause itching or eczema. High ferritin can point to iron overload (hemochromatosis), sometimes associated with hyperpigmentation ('bronze skin'). However, ferritin is an acute-phase reactant – inflammation, infection, or liver disease can elevate it independently of iron stores. Self-tests (capillary blood) are less accurate than venous draws, and timing, food intake, and inflammatory markers (CRP) should be considered. Without medical guidance, misinterpretation is risky: iron deficiency may stem from celiac disease or blood loss, and unmonitored iron supplementation is dangerous (oxidative stress, organ damage). For skin changes plus abnormal ferritin, consult a doctor for a full iron panel (serum iron, transferrin, transferrin saturation, ferritin, CRP). Evidence: practice-based, mechanistic.
