This study was performed on 30 diabetic and healthy controls. Fasting blood glucose, glycosylated albumin, glycosylated hemoglobin, fructoseamine, total protein, globulin and albumin were assayed in both groups. Albumin was isolated from the serum by precipitation using 22.2 % sodium sulphate and the glycosylated albumin level determined by the TBA method. Other parameters were determined by commercial assay procedures. A good correlation was found between glycosylated albumin and hemoglobin Alc and fructoseamine values. All of these levels were found to be significantly higher in the diabetic patients. However no significant difference was found in total protein, albumin, globulin and hemoglobin levels.
