Knowing Your A1C
The A1C test measures your estimated average blood sugar over the past 2 to 3 months. It’s like a “memory” of your blood sugar levels. It shows how well you’re controlling your blood sugar over time. Both your A1C and your blood sugar levels indicate how well you’re managing your diabetes.
Examples of A1C levels and how they relate to average blood sugar levels
When you get your A1C result back from the lab, you may see a blood sugar reading next to it. This is another way of showing your average blood sugar levels using the same measurement that you see on your meter, mg/dL (milligrams per deciliter).
