Abstract

Background: We assessed whether glycated albumin (GA) is a useful glycemic indicator in diabetic patients with anemia who did not undergo dialysis.

Methods: Hemoglobin A1c (HbA1c) and GA were simultaneously measured in 370 diabetic subjects who had not undergone dialysis. The relationship between GA and HbA1c was evaluated in patients with and without anemia.

Results: GA-to-HbA1c ratio was significantly higher (3.3±0.7 vs. 2.8±0.5, p<0.001) and the regression slope between GA and HbA1c was steeper in diabetic patients with than in those without anemia (6.2 vs. 4.2, p<0.001).

Conclusions: HbA1c was underestimated in diabetic patients with anemia than in those without anemia, with the degree of underestimation increasing as glycemic control became poorer. GA may more accurately assess glycemic control in diabetic patients with anemia than HbA1c.

Keywords: anemia; diabetes mellitus; glycated albumin; HbA1c; macroalbuminuria
