Hi @A DiabetesTeam Member.
There are at least 2 fasting blood glucose numbers you see here. The USA numbers mg/dL, and the numbers mmol/L, that most of the rest of the world uses.

Less than 126 mg/dL is a great fasting USA number.

That same number is 7.0 mmol/L.

So that number looks like a A1C number. But it is not.

An average number of 7.0(126) over 3 months would give you an A1C of 6.0.

So you see that the the fasting blood glucose numbers you see from countries not the USA are not A1Cs, even though they look much like them.

I believe that answers your question fully. I wish for you more good days than bad and have many exceptional days too.

We all learn as we go along. Baby steps. I can do baby steps and you can too.

Do you have another question now. We would be glad to help you.

And never give up, never surrender, never ever.
You got this.
Have a wonderful day.

You can't

A1C is the "average" of your highest and lowest blood sugars over a period of 90 days

You can get "close" if you test your fasting (usually your lowest number of the day but not always) AND your potentially highest number of the day - often 2 hours after the most "carb intense" meal of the day (for most of us this would be supper)

So if your "fasting average" is say 95 and your 2 hour post meal average is say 155 your "average" blood sugar level would be the midpoint between the two

155 - 95 = 60 (so in this example the blood sugar is in about a 60 point range on average)

60/2 = 30 (half of the range)

95+30 = 125 "average" blood sugar (half the range added to the lower number gives you the midpoint/average or subtract half the range from your higher average number as in 155-30)

Then use an A1C calculator like this one from the ADA: professional.diabetes.org/diapro/glucose_calc

And a eAG (estimated Average Glucose) of 125 equates to an A1C of 6.0%

I have had learned so much from the team members. You have explained it to me and I actually understood what you were saying. Thank you for your encouragement. I will never give up the fight. Have a blessed day.

If you test at least twice a day usually your meter will give you an average (weekly, monthly or whatever)

You can use that number and plug it into the A1C calculator

But if you ONLY test FBS or only after meals you are only getting half the picture - you need both numbers, averaged over a period of time, to equate to A1C

And the meters are pretty close - when I was doing two stick tests a day (fasting and after supper) my average equated "close enough" that there was no surprise on the lab test

I understand. Thank you for explaining it to me. I get my A1c checked in October.
