Iron deficiency is typically diagnosed via blood parameters: ferritin (storage iron), transferrin saturation, serum iron, and hemoglobin. Ferritin is the most sensitive marker, but as an acute-phase reactant it can be falsely elevated during inflammation – measuring CRP helps. Newer markers like hepcidin or soluble transferrin receptor (sTfR) are more specific but not yet routine. Direct-to-consumer tests (e.g., home test kits) often measure only ferritin or hemoglobin – useful for a rough screen but not a substitute for clinical evaluation. Genetic tests for iron deficiency (e.g., TMPRSS6 variants) are scientifically interesting but clinically not recommended because environmental factors (diet, blood loss) dominate. Important: Do not supplement based on a single low ferritin value – iron overload (hemochromatosis) is a real risk. Always consult a doctor for unexplained fatigue, pallor, or hair loss. Evidence: strong for standard lab methods, moderate to mechanistic for home and genetic tests.
