# A true A1c chart?

All the image searches I find have different ranges. What average BG does it take to get in the 5% club? For now in the last 30 days I show an average at 130 on my meter. I'm getting better with not spiking as high when I do my bootcamp workouts. That is the typical times it ever can go as high as 185 after some workouts. I've gotten as low as 135 a couple times. Still trying to figure that out. It's tough since its an early morning workout.

# A true A1c chart?

A1c measures the percentage of hemoglobin cells in your blood that have bonded with glucose molecules. Since the hemoglobin cells have a life span of 90 days on average, A1c reflects your average blood glucose over that period. since some hemoglobin cells are replaced more quickly than 90 days, A1c reflects recent blood sugar levels to a greater extent.

How that correlates with your average meter reading depends a whole lot on when you test. If you only test fasting and before meals, when your blood glucose is lowest, your average meter reading will be lower than your A1c might indicate. And if you only test after meals, looking for the highest spike, your A1c will be lower than that average. Most of us check a combination of both times, which makes an apples to apples comparison more difficult. When we are not testing, which actually is most of the time, are we closer to our lower fasting number, or to the higher numbers after meals? Without checking all the time its hard to know for sure.

Meanwhile A1c is a reflection of average blood glucose levels 24/7 for the last 3 months. Although it is related to blood sugar levels, it is not measuring the same thing exactly and so the relationship has been open to discussion. Up to about 2 years ago there were two main charts circulating that attempted to match A1c with average glucose, and they were about 10 points apart.  The ADA and other scientists, including Dr. Nathan, who had devised one of the original charts (which used the Nathan formula) came up with a new equivalency formula that is now the (mostly) accepted standard, although you can still find the old formulas and charts on the web. This page allows you to type in an A1c level and get back the equivalent estimated Average Glucose, or eAG, by the new formula, and you can also do the reverse. The links on that page explain this all in much greater detail.

But it cannot correct for the fact that your meter average reflects largely the times that you choose to test.

# A true A1c chart?

Yea, I figured this will not give me a true A1c reading since I test sometimes frequently at my highs and at all different times. I'm just using it to kinda get a close answer. Sometimes it reflects pretty close to what my A1c will be. But you never know!!!

# A true A1c chart?

Hi Kitty.....it took me a long time to keep my numbers below 90......so...with numbers between 60 and 85 will get you into the 4% club.....with a margin of error  I could be 5%.
I don't think it is an exact science because everyone is different, I have a friend that says she never goes over 120 and her A1c was 5.1....go figure.

You are doing well for a newbie........I have to change up my exercise program every two weeks to keep my girlish figure....teeeheeee!!!  Exercise is good for me.....it brings my numbers down.

See ya.............................Big Red.......................Peace

# A true A1c chart?

The chart that Jonas included is one of the old charts that can still be found on the internet--for example, that one can be found HERE at Ashley's Diabetic Center

The newer chart developed by the ADA comes up with different values. For example a 5.0 A1c is listed inthe post above as  equivalent to a 90 average, whereas the ADA formula yields an equivalency of 97.  As someone with an A1c of 5.0, my instinct is that 97 is closer  to the truth than 90.  At higher A1cs, the difference is a bit less: the chart lists an average glucose level of  120 and 150 for A1c's of  6.0 and 7.0, whereas the ADA  forumula suggests that  that 126 and 154 would be the equivalents. At very high levels, above 10, the ADA formula yields a slightly higher, though very close result to the chart above.

# A true A1c chart?

Here's a brief version of the new chart.

The relationship between A1C and eAG is described by the formula

28.7 X A1C – 46.7 = eAG.

Now that's not exactly the kind of math I can do easily in my head, but if you think about it for a while, or try it out, you'll see that to raise or lower your A1C by 1.0%, you have to raise or lower your average blood glucose by 28.7mg/dL

Here is the chart I use. http://www.diabeteschart.org/bloodsugarchart.html
I think it is pretty extensive and I find it pretty accurate.
