Glycolisated hemoglobin (HBA1c), fructosamine, glucose, albumin and total proteins were estimated 40 healthy pregnant women and 90 pregnant women with diabetes mellitus. Fructosamine was estimated by NBT method with "Fructosamine test" commercially available kit on Technicom automatic analyser RA-1000. Glucose was determined on Beckmman glucose analyser. HBA1c was assayed by Bio-Rad test, while albumin and total proteins by Beckmman tests. We found best correlation between fructosamine and HBA1c at pregnant women who were on dietary therapy worst at pregnancy women on insulin therapy.
