What role does Eisen-Ferritin Selbsttest play in Stress?

The role of an iron-ferritin self-test in stress cannot be determined from the provided context. Ferritin is an iron storage protein and also an acute-phase reactant that can rise during inflammation, infection, or physical stress. A self-test typically measures only ferritin levels in blood, not other stress markers like cortisol or inflammatory cytokines. Interpretation is complex: elevated ferritin may indicate iron overload or chronic inflammation/stress; low ferritin suggests iron deficiency, which can cause fatigue and reduced stress resilience. Without medical evaluation and additional tests (e.g., CRP, transferrin saturation), the test is not suitable for stress assessment. The evidence for a direct link between ferritin self-testing and stress is unclear; it is a mechanistic approach lacking clinical validation for this purpose. Safety note: self-tests do not replace professional diagnosis. For stress symptoms, comprehensive medical workup is recommended.
