Iron Store Estimator (Ferritin)
Estimate total body iron stores from serum ferritin. Size-independent rule: stored iron (mg) ≈ ferritin (µg/L) × 10. Body-weight estimate (better across body habitus): stored iron (mg) ≈ ferritin × weight(kg) × 0.0024 (Walters 1973). Adult ferritin reference: men ~30–300 µg/L, women ~15–150 µg/L. Ferritin < 30 µg/L (men) or < 15 µg/L (women) strongly indicates iron deficiency; < 100 µg/L in an inflammatory state does not exclude it. Ferritin > 300 µg/L (men) / > 200 µg/L (women) with TSAT > 45–50% suggests iron overload (hereditary hemochromatosis, dysmetabolic iron overload, iron-loading anemias, transfusions, chronic liver disease); > 1000 µg/L warrants evaluation of hemochromatosis, iron-loading anemias, or hyperferritinemic syndromes. Ferritin is an acute-phase reactant — interpret with TSAT and CRP. Derived from Camaschella 2019, Adams NEJM 2005, and WHO 2020. Not medical advice.
Quick start
Call this tool from your code in three languages.
curl -X POST 'https://api.elysiatools.com/en/api/tools/ferritin-store-estimator' \
-H 'Content-Type: application/json' \
-d '{"ferritin":12,"weight":0,"sex":"female","method":"size","decimalPlaces":1}'API reference
Send a POST request with your inputs as JSON. File parameters require a separate upload first.
Endpoint
POST https://api.elysiatools.com/en/api/tools/ferritin-store-estimatorParameters
| Name | Type | Required | Description |
|---|---|---|---|
| ferritin | number | Yes | Serum ferritin in µg/L (equivalent to ng/mL). Adult reference: men ~30–300, women ~15–150. |
| weight | number | No | Body weight in kg. Optional; required only for the body-weight estimation method. |
| sex | select | No | Used to select sex-specific ferritin reference thresholds (men 30–300, women 15–150 µg/L). |
| method | select | No | Size-independent rule (stored iron ≈ ferritin × 10) or body-weight rule (ferritin × weight × 0.0024). |
