What Is A1C?

A1C (also called HbA1c) is a blood test that measures your average blood sugar over the past 2-3 months. It is the primary test used to diagnose and monitor diabetes and prediabetes.

This is an estimate based on your average meter readings. Your actual lab A1C may differ due to factors like anemia, hemoglobin variants, or how consistently you test. Always get a lab A1C from your healthcare provider for an accurate diagnosis.
