I am a type 2 and take my blood three times a day. Can someone tell me the formula to use to figure an A1C from three months of these numbers?
Asked By: dunigan  

Background Info Hide
I have over 270 readings a month going back a long way. I have charts that give me an approximate correlation between a daily number and an A1C, but if you haven't guessed I am a little more anal than that.

Hello Dunigan Thank you for bringing your question to dLife. There ia a chart that gives the relationship between averages of glucose readings and the A1c level that you can expect to see. So if you can figure out what your average glucose level is with all those readings, you can estemate what your next A1c will be. I hope this helps: CORRELATION OF A1c WITH MEAN PLASMA GLUCOSE AVERAGE HbA1c% mg/dl Mmol/L 6 126 7.0 7 154 8.6 8 183 10.2 9 212 11.8 10 240 13.4 11 269 14.9 12 298 16.5

Here is the formula I know: (glucose+77.3)/35.6 To estimate avg glucose based on A1c: (A1c*35.6)-77.3

I would add one factor to the expert's answer. If you check 3 times a day you could easily miss a particular time of day when your BG is higher or lower than the three times you do check. If you check three times a day and they are all before meals I would expect your A1c to be higher than these numbers indicate whereas if you check 3 times a day after meals or at a time you have pronounced dawn phenomenon I would expect your A1c to be lower. Congrats on your dedication to checking and trying so hard to manage your diabetes.
