I am doing at home A1C tests every month to see if it jibes with my sensor average.
This month it came in at 6.1, which indicates an average glucose of 128 mg/dl for the past 3 months. It's heavily weighted on the last month, but also shows a longer reaching trend.
It's my best (likely valid) result that I've had in my diabetic life. I'm happy about it.
During the past year I have tested between 7.8 and 6.7 (which translates to averages of 177-146 mg/dl).
My goal this year is to get into the 5s.
