Iron Deficiency Anaemia Calculator
Calculates total iron deficit using the Ganzoni formula and interprets iron studies to differentiate iron deficiency from other causes of anaemia.
Score interpretation
Target Hb achieved. No iron repletion required.
→ Maintain current status. Monitor for ongoing losses.
Iron deficit 1-500mg. Oral iron supplementation usually sufficient.
→ Start oral iron (ferrous sulfate 200mg TDS). Recheck Hb in 4-8 weeks. Treat underlying cause.
Iron deficit >500mg. Oral iron may be insufficient or intolerated.
→ Consider IV iron (ferric carboxymaltose or iron sucrose). IV iron preferred if malabsorption, intolerance, or rapid repletion needed. Haematology review.
