How are glycated hemoglobin (HbA1c) and estimated average glucose (eAG) related?
HbA1c (glycated hemoglobin) is used to evaluate the blood glucose of diabetes patients across the preceding 2-3 months. Results are shown as a percentage which can be confusing for those more familiar with mg/dL or mmol/L glucose units. The American Diabetes Association, the European Association for the Study of Diabetes, and the International Diabetes Federation worked together to develop a global standard with which to interpret the relationship between HbA1c and estimated average glucose (eAG). The formula is as follows:
(28.7 x HbA1c) - 46.7 = eAG
