So you tested 5 times, if each test covers 1 minute of blood sugar. A day has 1440 minutes in a day and you tested only 5 of them. I would expect that the meter A1c is going to be way off of the actual A1c
I know it may be off, but curious how off the sugar sence app is from a doctor office visit? If the app shows a1c 5.9 but your doctor says its 6.9 then while using the app you know to add a point.
