The present study was undertaken to find out any correlation between serum zinc concentration and HbA 1C % in patients with type 2 diabetes mellitus (DM). The study was carried out on 50 newly diagnosed patients of type 2 diabetes and controls in the Department of Biochemistry, Assam Medical College and Hospital, Dibrugarh. Analyses of blood glucose (fasting and postprandial), glycated hemoglobin (HbA 1c ), serum zinc, urea, and creatinine concentrations were performed by standard methods. Concentrations of fasting and postprandial blood glucose were significantly higher in the diabetic group than controls ( P < 0.001) and the mean HbA 1 c% was also higher in cases (8.32% ±1.58%). The mean serum zinc concentration in cases was found to be significantly lower than controls (79.85 ± 13.4 vs. 109.74 ± 9.72 μg/dL) and P < 0.001 with correlation coefficient r = -0.804. Present study revealed an inverse relationship between HbA 1C % and serum zinc concentration in patients with type 2 DM, substantiated by regression analysis.
