Does anyone have a formula to convert blood sugar test to A1C

Here you go! gives the estimated blood sugar number for the A1C

This formula estimates BG readings from A1c, not A1c from BGs as this question requests.

um just reverse it! If your BGs are average at 140, your A1C would be about 6.5. But as stated previously it is JUST a baseline guideline.

Not really. You wake up at, say, 80; you eat and it goes to 135 in 2 hours; then it may drop to 90. Your A1c is a THREE month average and doesn't bounce around with each individual reading.

dont let the converted bsl be your guide, much better to buy the real tester at your local pharmacy because unless you test every minute, it wont be accurate..

I have found an app for the iPhone. "Pancreum" has an A1c converter that does give me a close approximation. My last two A1c test at the Dr was within .1 of the results I had. I also use an app from dLife to track my BS daily tests. It will also give me a 7,14, 30,and 90 day average that I can plug into the converter to get the A1c approximation. I don't know if these are available on the computer since the iPhone is my way of constantly tracking my tests as well as my food log.

Yes they are right its a three month average. When I was diagnosed the doctor scheduled me for a test one month later. I kept my numbers really low for that month as I now knew I was diabetic. On the one month mark my alc was something like 7.4 if I remember correctly, however my daily readings had me in the 5's.
I had to remind my doctor it was a snapshot of two months without a diet of meds and one month on. The reason for this is that the life span of a blood cell is approximately 90 days. Each cell stores what ever damage it has during its life span. Your better reading only changes that for the new cells developed not the older ones .There are charts but it can not really be accurate for the reasons mentioned

I disagree because if the lab can formulate your a1c then there is a formula

TsalagiLenape 2012-06-13 00:29:44 -0500 Report

Its not a formula per se…Its measuring out the percentage of your glycated hemogloblin aka Hemo Globin A1C…this deals with the sugar our bodies have in it. Thus if your pancreas and etc isnt working right or at all, this lets the doctor know. Jayabee do get a hold of Byrun! I just passed my clinicals in Phlebotomy!

im not sure if its a formula they use.The A1c is determined by measuring the percentage of glycated hemoglobin hbA1c that is in your blood

you can disagree all you want JSHIN. I gave you what is available on the web. Perhaps Byrun, who used to be a lab tech could enlighten us, if he is here on the site. I'll see whether he is around and what he has to say about this.

Howdy Jshin! WELCOME to DiabeticConnect!

The A1c is a running average of one's Blood Glucose readings for 24/7 of the past 3 months which gives more weight to the past 2 or 3 weeks of the 3 months (90 days).

To find one's A1c you really need to go to a Dr and have an A1c test done. (Or there are special meters you can use to get an approximation of one's A1c, but they and the strips to do the A1c are rather pricey)

There is a calculator and a chart I have found on the web which gives a rather static (as opposed to dynamic — snapshot versus movie) feeling for what one's A1c might be. But mind you it may not be accurate as it is only a "snapshot" of what your A1c might be like at one particular moment in time.

That calculator and chart may be found here ~ http://healthy-ojas.com/diabetes/a1c-glucose-...

Blessings to you and yours!
