What to watch with Eisen-Ferritin Selbsttest and stress?

The iron-ferritin self-test measures ferritin as a storage marker, but stress can confound results: acute stress raises cortisol, which inhibits iron release from stores, while chronic stress via inflammatory cytokines (e.g., IL‑6) elevates ferritin as an acute-phase reactant – a high ferritin may falsely suggest iron overload when storage iron is actually normal or low. Ferritin also shows diurnal variation and rises during infections. A single self-test is a snapshot, not a diagnosis. Watch for overlapping symptoms like fatigue, poor sleep, or frequent infections, which could stem from either stress or iron deficiency. Consider pairing the test with a CRP measurement to detect inflammation. If results are abnormal or stress is chronic, consult a doctor for a full iron panel (serum iron, transferrin, transferrin saturation) and possibly a cortisol day curve. The test is a screening aid, not a medical decision tool – interpret it together with lifestyle and clinical context.
