What is A1C??

I have had several readers ask, "What is A1C?"

Of course, prior to Alyssa's diagnosis, I didn't know either.

Basically, A1C is a blood test that reflects patients blood glucose levels for the past 2-3 months.  Specifically, the A1C test measures the percentage of hemoglobin (the protein in red blood cells that carries oxygen) that is covered with sugar.  The higher the level, the higher average of blood sugars and the higher the risk of complications.

A normal A1C is between 4.5-6%, which means an average of 80-135 mg/dl (blood sugar levels).  An A1C 6.5 or higher indicates diabetes.  There is also pre-diabetes which is an A1C of 5.7-6.4%.  For most adults with diabetes, the ideal target is an A1C of 7% or lower (average bg's 170 or lower).  With children, the target is 8 % or lower (average bg's 205 or lower).
