Default A1C online calculators

I've used several online calculators to give me an idea what my A1C is between doctor visits and found this important fact out: If I use my average morning fasting reading the results almost perfectly match my A1C. If I instead use my meter's average reading, it's much higher.

So the moral of the story is: the A1C online calculators (like linked below) are pretty good indicators of what's happening if you use your fasting average.

Not sure what you are saying, your meter average is higher or lower than your fasting numbers? If mine were opposite of yours, my A1c may closer match my average than my fasting, but without having way more test results in our meter than most of us have, our fasting or total averages may or may not reflect what our BG is day in and day out. It is only what it is at those particular moments and if it matches an A1c, it is likely just coincidence.

My meter average is higher than my fasting numbers by about 25 points. One reason is I took a lot of post-prandial readings over the past several months which are, obviously, higher than my average.

More to my point though is the fact that my average fasting readings — which is about 103 — matches my A1c quite well. Further, my initial readings on diagnosis (360/12.4) work in harmony with the online calculators.

So my point is that, at least for me, my fasting readings pretty much tell me what my A1c is and I don’t need to wait for the doctor to tell me that.

I’m wondering if others have the same experience.

My last A1c was 5.3 and back calculating that would be about a 105 average. My fasting average was 90 or less, which would be about a 4.8 A1c, but the calculator only accepts numbers between 100 and 300.

My point was that using fasting numbers to estimate an A1c is not a universal rule of thumb, nor would meter average be consistent unless you tested 200-300 times per day (every 5 minutes) for 3 months.

LOL Me neither. I need my beauty sleep.

Makes me wonder though, how close a well kept cgm is at matching an A1c.

I tried the above calculator using the average of my readings in my computer program. I've cut my A1C almost in half. I'm a happy camper and I know my doctor will be too.
