What is the significance of an A1C? And does anyone know what an EAG is? I had to call my dr office to get my results of the test I did 3 weeks ago and she said my A1C is 7.5 and my EAG was 168. The nurse didn't know what these were, and the dr wasn't in. Thanks!

A1C is a test that gives an average of your blood glucose levels over the past 2 to 3 months. I found information on A1C at:


Your EAG is an estimated average glucose. This is a new test that is coming out that maybe a bit more accurate. I found this information at:

How the heck can it give an average over 2-3 months if this is the first one I had? Mind boggling! Thanks I will check those sites out!

Even though this was your first A1C it doesn't mean you just became diabetic. Many diabetics don't know they even have it for years sometimes. Therefore, this test is done to give an average.
For instance, my daughter started showing signs of diabetes last Nov. and A1C was done in early October but, she had a normal level, they retested her in January and her level was over the normal range but they thought it to be pre-diabetes at that time. In early February she was diagnosed T2 diabetic leading to T1. We just recently had more tests ran and it looks like she is approaching the end of her honeymoon period and getting closer to T1 and further from T2. Also, she could be in the class of Double Diabetes, having characteristics of both types of diabetes.
It takes some time to get any diabetic on the right track and all these tests are necessary. There may also be several medication changes until the right combination is found as none of us are exactly alike and there is no universal treatment for us.

A1C tests should be done every 3-6 months depending on your situation and control.

7.0 and above every 3 months
6.9 and below every 6 months.

Guidelines my doctor uses.
