CPE-004 · Iron status
ID-ST-01: Iron stores depleted (ferritin below 15)
Iron stores depleted (ferritin below 15). Evaluates ferritin below 15 ng/mL.
Condition
- ferritin < 15 ng/mL
- no inflammation or CRP elevation changing the cutoff
What it reports
- Iron stores depleted: absolute iron deficiency criterion met (WHO)
Recommended next steps (for physician review)
- Look for the cause: blood loss, diet, absorption and increased demand
- Complete iron studies and a CBC if not recent
Diagnostic boundary
- A criterion for iron deficiency, not a statement about its cause.
Evidence
- EV-WHO-FERR-2020World Health Organization. WHO guideline on use of ferritin concentrations to assess iron status in individuals and populations. Geneva: WHO; 2020.Supports: Ferritin below 15 µg/L indicates iron deficiency in healthy adults A higher cutoff (<70 µg/L) applies in the presence of infection or inflammation
- EV-CAMASCHELLA-2015Camaschella C. Iron-deficiency anemia. N Engl J Med. 2015;372(19):1832-1843.Supports: Stages of iron deficiency, causes and differential diagnosis of microcytic anemia
