What Does an Estimated Average Glucose (eAG) Number Tell you?

Chances are you took your blood sugar today, so you knew your fasting glucose levels or your glucose levels after a meal. And most likely, you go to your doctor at least twice a year for an A1c test, which tells you what your average blood sugar has been over a period of several months.

All these numbers can be confusing, but new research has found a way to bridge the gap between daily glucose monitoring and A1c tests. It's called the 'estimated average glucose', more commonly know as the eAG number.

What is The eAG?

The eAG is not a new test-- don't worry, it won't require another stick. Rather, it's a new way to calculate and present the information gained from the A1c test.

The American Diabetes Association recommends that health care providers present diabetics with the eAG numbers to help us better understand how the long-term numbers correspond to what we’re reading each day on the glucose meter.

How Does This Work?

Your daily monitoring levels read out at mg/dl (or mmol/l), and your A1c gives you a percent number. The eAG will tell you how they are related by translating your A1c into mg/dl (or mmol/l).

For example, you might have been told that your A1c is 7 percent, which is fine and dandy-- but what does that say about your blood glucose average?

The eAG translates that so you know your average daily glucose level is 154 mg/dl (or 9.57 mmol/l). Now your short-term and your long-term glucose level readings are on the same page, and easily comparable—thanks to your eAG.
