|Estimated Average Glucose|
Estimated average glucose (eAG) is a glucose concentration level calculated from a patient's HbA1C result. In 2008, the ADA recommended the use of this new term and that this calculation be performed and reported routinely with the measured A1C result. The formula for conversion of HbA1C to glucose in mg/dL is eAG = 28.7 x A1C – 46.7. A web calculator is located at: http://professional.diabetes.org/glucosecalculator.aspx. Accessed January 11, 2010.
