My daily finger sticks usually run between 120 and 135, yet my A1C results are always under 7. In fact, the latest was 6.1. How does that happen?

Thanks for asking dLife.

A1C is a blood test that measures the amount of glycated hemoglobin in the bloodstream over a 3-month period. Glycated hemoglobin is produced when excess glucose sticks itself to hemoglobin (red blood cells). The American Association of Clinical Endocrinologists (AACE) recommends people with diabetes aim for a target A1C level of 6.5 percent or lower. Your A1C at 6.1 meets the goal! A1C in the target range is associated with fewer complications of diabetes.

These expert answers just keep getting worse, why? The question was NOT what is a good level, it was why are the blood sugars of fingersticks 120-135 but the A1C was 6.1? Here is a correlation chart for leetoo. http://www.rajeun.net/HbA1c_glucose.html It will show you that a 6.1 correlates to a 140 blood sugar. That being said ... conversions from an A1C to an average blood sugar are just that - a correlation. An A1C actually measures the amount of glucose sticking to the cells. It is not some statistical average. Even if it were a statistical average, our fingersticks are one moment in time and could never, statistically come out to what an A1C says. And let's not forget the FDA permissible 20% inaccuracy rate of home glucose meters - which vary with range. Most recently, Dr. Bernstein changed found the Abbott Freedom Lite is the most accurate meter these days but noted that's only within the 80-100 blood sugar range. All bets are off outside of that range. He used to advocate for the Aviva but it appears it's accuracy has fallen off ... I think they are not made overseas.
