Can Eisen-Ferritin Selbsttest help with Langlebigkeit?

An iron-ferritin self-test can provide insight into iron status, but its direct relevance to longevity is limited. Ferritin is a storage protein for iron; both deficiency and overload can promote oxidative stress and are linked to aging processes. However, the evidence for a causal relationship between ferritin self-tests and extended lifespan is weak, based mainly on mechanistic and observational data. Such a test may serve as a screening tool but does not replace clinical diagnosis. Interpretation should always consider other biomarkers (e.g., CRP, transferrin) and individual context. Without accompanying clinical evaluation, its utility for longevity remains unclear.
