You can estimate A1c from average BG, but that average is not simply the

numerical average of your meter readings. I've written a booklet about this.

It's

free and will be accessible on my web site which will be up in a couple of

weeks.

What is the difference between an A1C reading and taking the average of

readings for the past three months? Couldn't we figure out the A1C

readings from that average? Or would it be very different?

[Guest guest]

My average BG's over 3 months

match the estimated A1c on charts

and the actual A1c measured in labs.

Here is a chart:

: perhaps if we had a continuous moniter recording all our bg's at

every single moment of every single day for that 3 months, one might be

able to estimate an A1c. Since however we are only getting a glimpse of

where we are at certain times when we do measure that in no way

corresponds to an A1c glycation average.

I've found I can get relatively close that way - but only when I test

many times a day. The problem, of course, is you're still only

getting an average - and you don't know what your body's up to

when you're not looking (sneaky thing that it is!)

Oops. He's right I had to compare my readings to a chart of

what Hba1C corresponds to the numbers we're used to seeing

on our meter. Duh!

The more often you test, the closer the estimate would be, but since

glycosilation takes place all the time, you'd never be 100% accurate.

:

Even if you were able to average a continuous set of readings from the

previous three months, it still might not equal the test results of the

lab. Often times, HbA1c readings are weighted more heavily towards the

events of the most recent few weeks, while those of the earliest month

or so are discounted.

That said, I've gotten some reasonable A1c estimates (+/- 0.2) when I

averaged my bg tests from the previous three (sample test set of at

east five times per day). I don't recommend that for everyone, but

wanted to offer the testimonial that you its possible to get a good

ballpark with some measure of frequent meter testing.

But what we really want to know is our average BG. So the continuous

readings would in fact be more accurate. The A1c is simply an imperfect

estimate of continuous readings.

If one wanted to know what an A1c would be, based on continuous readings, it

should be fairly simple to come up with a formula that would do the

weighting. I think some of the diabetes software programs come up with

estimates. I don't know if they do weighting or not.

I've heard that before on this list and mentioned it to my nurse

practitioner. She said she'd never heard of that and asked if I had any

references for it. So I'll ask you if you have some references.
