The measurement of glycosylatedhemoglobin (HbA1c) is one of thecornerstones of management of dia-betes. Most physicians use HbA1c values in the assessment of a patient’s control of their blood glucose levels and as a reality check for home glucose-monitoring results. A target value of 7.0 % is widely regarded as excellent glycemic control (1). Good glycemic control is associated with lower rates of microvascular complications from diabetes in both type 1 (1) and type 2 (2) diabetic patients. Changes in therapy are often based on HbA1c values. Some patients attending out-patient clinics for diabetes management were noted to have HbA1c values that dif
