Just got my lab results and lo and behold my A1c is 5.4. Doesn’t make sense as my meter average and my CGM average is at least 119. that doesn’t correlate to a 5.4 and besides, I’ve been getting A1c results for over 35 years. Usually they come out around 6.1, give or take. The previous one was 5.7. So…I Googled, and found this:
Average BG = 28.7 x A1c - 46.7
Using that formula, the A1c indicates my average bg is 108. I wish! I’ve had this disease too many years to think that could be my average, even if you pretend my meters and CGM’s are inaccurate over the course of the last 2, or 3 months. I ran reports for various time ranges and didn’t get an average that came close to the A1c.
What I’m saying is I’ve had SO MANY A1c tests over the years, I think the lab made a bit of a boo-boo. (I’ve been diabetic since sometime prior to 1978, which was the year of my belated diagnosis)
