Continue reading >>, Jonathan's fasting glucose: 85 mg/dl Jonathan's high HbA1c reflects blood glucose fluctuations over the preceding 60-90 days and can be used to calculate an estimated average glucose (eAG) with the following equation: (For glucose in mmol/L, the equation is eAG = 1.59 A1C - 2.59) Jonathan's HbA1c therefore equates to an eAG of 145.59 mg/dl--yet his fasting glucose value is 85 mg/dl.
