Changes in Serum Ferritin Levels after Intravenous Iron

Abstract
The effect of intravenous iron dextran on serum ferritin levels was observed in two patients with iron deficiency anaemia. Serum ferritin levels rose sharply and reached peak levels seven to nine days after infusion when at least 90 % of the infused iron had been removed from the plasma. A linear relation was shown for each patient between the logarithm of the serum ferritin levels and the logarithm of the calculated cellular non-haem iron levels.
