HbA1c product of non enzymatic glycation of HbA increases in relation with the mean blood glucose level during the former 2-3 months. HbA1c levels are correlated with the development of diabetic complications and HbA1c assessment is now the gold standard for evaluation of diabetes control. HbA1c level should not be higher than 7% to avoid these complications. However, in aged peoples, the objectives of diabetes control vary according to their health status. It must be good with HbA1c lower than 7-7.5% in healthy subjects and more relax in subjects with symptoms of frailty and risks of non perceived and self corrected hypoglycemia. Under these conditions, HbA1c values lower than 8 to 9% are advised. Nevertheless, hypoglycemia episodes may occur in patients with high HbA1c and capillary glucose follow-up is necessary for detection of such complications.
