Myths vs facts: Eisen-Ferritin Selbsttest and menopause

Iron and ferritin self-tests during menopause are a mix of myths and facts. Fact: Ferritin is a storage protein for iron, and its blood level reflects iron reserves. In menopause, ferritin often rises because menstrual blood loss stops, which can lead to iron overload associated with oxidative stress and increased cardiovascular risk. A self-test could theoretically help detect excess. Myth: A single ferritin value without additional markers (CRP, transferrin saturation, hemoglobin) provides a reliable assessment of iron status. Ferritin is an acute-phase reactant; inflammation, infection, or chronic disease can skew results. Moreover, home tests are often not standardized or certified, compromising accuracy. Evidence for the benefit of such self-tests in menopause is weak, based mainly on mechanistic reasoning rather than clinical trials. Women in menopause should prefer physician-supervised lab diagnostics, especially if symptoms like fatigue, joint pain, or hot flashes occur. A self-test may serve as a rough orientation but does not replace professional evaluation. Caution: Low ferritin may indicate iron deficiency but can be masked by inflammation. In summary, self-tests offer low-barrier access but should be interpreted cautiously and not used as sole basis for supplementation decisions.
