Anemia is a common complication of chronic kidney disease (CKD).1 Anemia refers to a decrease in the number of RBCs or the amount of hemoglobin in the blood. It is relatively uncommon in stages 1-2 of CKD; however, almost 90% of patients with a glomerular filtration rate (GFR) less than 30 mL/min are anemic. Also, the prevalence of anemia in CKD increases as the CKD stage increases. For the evaluation of anemia in CKD, the initial tests must include a variety of tests, including complete blood count (CBC), serum ferritin, serum transferrin saturation (TSAT), absolute reticulocyte count, serum vitamin B12 and folate levels. Iron therapy is a commonly adopted approach for the treatment of anemia in CKD.2
