Improving accuracy, ensuring consistency – the future for reporting HbA1c

Globally, where the test is available, the measurement of haemoglobin A1c (HbA1c) has become central to the management of diabetes. By giving an objective assessment of glucose control over the preceding 2 to 3 months, it can guide treatment decisions in a way that single blood glucose measurements cannot. The authors describe efforts to standardize and improve the way HbA1c is reported, and explain the practical implications of the recent changes in the way the test is measured.
