What is an A1c Test?

The A1c Test is a common blood test used to diagnose Type 1 and Type 2 Diabetes
and then to gauge how well you’re managing your diabetes.
The A1c Test result reflects your average blood sugar level for the past two to three
months.
Specifically, the A1c test measures what percentage of your hemoglobin (a protein in
red blood cells that carries oxygen) is coated with sugar (glycated). The higher your
A1c level, the poorer your blood sugar control and the higher your risk of diabetes
complications.
