Iron Deficit Calculator






Notes

  • The most common parenteral irons are Venofer and Cosmofer.
  • This calculation is based on Ganzoni formula.
  • Total iron deficit (mg) = [Booking weight (kg) × (target Hb – actual Hb) × 2.4] + iron storage (mg)
    • <35kg: Target Hb = 13 g/dl and iron storage = 15mg/kg
    • ≥35kg: Target Hb = 15 g/dl and iron storage = 500mg
  • This calculator is not meant for weight <35kg to avoid confusion.
