Can someone please explain the differences among these three glucose test terms?
1. Average Glucose A1C
2. Hemoglobin A1C
These terms were taken form a pamphlet about diabetes. I never got a chance to read it all. I know, of course, what glucose is. And I understand what "average glucose A1C is. Hemoglobin A1C is, I suppose, blood glucose. I never heard of that. My curiosity is how does each differ from the other two? Why three different kinds of tests? Thank you.
