I use the conversion tool on Accu-Chek.com. How reliable is that compared to the conversion table you have supplied? Just wondering if I need to quit using that one, because their seems to be a big difference in the end result. Thanks for the post. Very informative.

The above chart seems to be off In a book by endo. Dr. John Merendino.,
the nos. are very different.(a1c 7 154).the chart is in the early pages of the book.
If you keep a log,you can see the BIG difference

If you research the conversion charts you will find more updated ones than the one I posted. Please note that the one i posted is dated July, 2009. What is the date of John Merendino's book? These charts do change with time.

It is good to know about blood sugar comparison!I check my sugar everyday but this is a different perspective!Since I am from Medical background
also logically keep in mind that the A1c is average of 3 months.It shows how your sugar level was within let's say March April & May if you get it tested in June.
Thanking you.

Oh, I am down to 6.1, don't know what I was before, but my Dr. said that he would like it a bit lower, but I had no idea HOW LOW etc. Thanks again! Pat Roth

Is this an average? As mine has been 160 to 190 a few times during the day, low maybe around 130, 140, which doesn't quite compute with 6.1——unless mine has been lower more than I have checked it. Is this right? PR

I meant, am I RIGHT? NOT the information! My fasting is usually 120 to 135 or so, about that at HS, but maybe it falls in between checks—just asking, I don't have a clue. thanks, PR

Hello Pat. Yes, the right column in the chart represents your average blood sugar levels from your meter over a period of time. If you kept your average over a three month period then that should tell you what to expect for your A1c for that three month period.

The A1c measures your average blood sugar level "continuously" over the three months but gives more emphasis to the last few weeks before the blood was taken from your arm. Your meter average includes only your blood sugar at the precise moments at which you tested. That is why your meter average and A1c average might not agree every time. If you test only a few times per day then they will be even less likely to agree.

Thanks for posting Richard! This is a little different than the one that I had saved. I always like to get updated information.

I am at 7.2 right now, so I hope that I will be getting something more along the lines of a 6.5 next A1c test.
