Introduction: Iron deficiency is an important cause of anemia in patients with chronic kidney disease (CKD). Anemia develops early during chronic kidney disease (CKD), affects virtually all individuals with stage 5 CKD (GFR <15 ml/min per 1.73 m 2 ), and is associated with increased cardiovascular morbidity and decreased quality of life. Iron deficiency is a common cause of anemia in CKD; the estimated prevalence ranges from 25 to 70%. The causes include decreased intake or absorption of iron; iron sequestration as a result of inflammation; blood loss; and increased iron use for red blood cell production in response to erythropoiesis stimulating agents (ESA). Inadequate production of erythropoietin by the kidney and/or insufficient response to erythropoietin as a result of inflammation contributes to anemia during later stages of CKD.Appropriate management of anemia in CKD often requires both iron and ESA. Thus, assessing
