Glycated albumin (GA) is thought to more accurately reflect glycemic control status in diabetic patients with advanced CKD or ESRD on HD than glycated hemoglobin (HbA1c), because the latter can be influenced by various clinical factors such as reduced red-blood cell lifespan, recent transfusions, iron deficiency, metabolic acidosis or frequent erythropoietin injection. So, HbA1c tends to underestimate the glycemic status. To test this, HbA1c and GA were measured in 50 diabetic subjects (of whom 25 were ESRD
