functional iron deficiency

A deficiency of iron significant enough to affect the development of healthy red blood cells. It may precede the appearance of measurable anemia.

Patient care

Functional iron deficiency may be defined by the presence of hypochromatic red cells; by an increase in hemoglobin production after test doses of administered iron; or, most accurately, by the measurement of the mean hemoglobin content of reticulocytes. It is common in patients receiving hemodialysis and in critically ill persons.

Treatment

Treatments include iron and folate supplements and epoetin alpha (Procrit) to increase red blood cell production. In emergencies, infusion of fresh frozen packed cells or washed packed cells provide temporary relief.
