Iron management in ESRD and the role of the nephrology nurse.

Iron deficiency is common in patients with end stage renal disease (ESRD) receiving recombinant human erythropoietin (rHuEPO). Consequently, such patients require routine iron monitoring by measurement of serum ferritin and transferrin saturation, with interpretation of these values in light of the response to rHuEPO. This article will review issues related to iron metabolism, the causes and diagnosis of absolute and functional iron deficiency, and treatment options for iron deficiency. In addition, the role of the nurse in iron management will be identified.
