What role does Eisen-Ferritin Selbsttest play in Langlebigkeit?

The iron-ferritin self-test measures ferritin concentration in blood, a storage protein for iron. Optimal ferritin levels are relevant for health: iron deficiency can cause anemia and reduced performance, while iron overload (e.g., in hemochromatosis) promotes oxidative stress and is associated with increased risk of cardiovascular disease, diabetes, and premature aging. However, direct evidence linking self-testing to extended lifespan (longevity) is lacking from robust intervention trials. Evidence comes mainly from epidemiological observations and pathophysiological models. A self-test can help detect abnormalities early but does not replace medical evaluation. Its predictive value is limited because ferritin also fluctuates as an acute-phase protein. For longevity, many factors matter – a single biomarker is insufficient. Evidence: mechanistic/observational, not clinically validated for longevity.
