Clinical Context

We think this might be relevant to the clinical guidance for Ganzoni Equation — Iron Deficit in Pregnancy.

Iron Deficit (Ganzoni)

Ganzoni Iron Deficit

Parenteral Iron Requirements

The factor 2.4 = 0.0034(iron content of Hb in %) × 0.07(blood volume as % of body weight) × 1000. 500mg represents average iron stores.

Guidelines & Evidence

Last Review: 2026

When to Use

When to Use

Calculation of total iron requirement in patients with Iron Deficiency Anemia (IDA).
Planning parenteral (IV) iron replacement therapy when oral iron is ineffective, not tolerated, or rapid replenishment is required.
Second or third trimester anemia where Hb < 10.5–11.0 g/dL and ferritin < 30 ng/mL.
Pre-operative optimization for patients with scheduled Cesarean sections and known anemia.

Clinical Thresholds in Pregnancy

Iron deficiency is typically defined as Ferritin < 30 ng/mL. In the presence of inflammation (elevated CRP), a threshold of < 100 ng/mL may be used, though this is less specific in the obstetric population.
