Can Eisen-Ferritin Selbsttest help with Haut?

An iron-ferritin self-test can provide a rough indication of your iron status, which is relevant for skin health (e.g., pallor in iron deficiency). However, the provided context lacks evidence for the clinical validity of such home tests. Accuracy may be affected by timing, diet, or inflammation. They do not replace professional lab diagnostics. For skin issues like unexplained pallor, hair loss, or brittle nails, a doctor’s visit with blood work (including ferritin, CRP, transferrin) is more reliable. Evidence: unclear – no robust studies from context. Caveat: self-tests may yield false low or high values and lead to misinterpretation.
