Your average blood glucose appears on your dashboard in Hedia, and it will show up after you have made 28 calculations over a period of (maximum) 14 days. The average blood glucose calculated by Hedia is an average of your entered blood glucose measurements in HDA
The amount of data within this time period is enough to provide a sufficiently accurate estimate of your average blood glucose.
Your average BG in Hedia is not the same as the HbA1c measurement that is measured by your doctor. The HbA1c measurement is reported as a percentage of the total hemoglobin in the blood, and the test is representative of a 2-3 month average.
