The A1C number (also known as HbA1c or glycated hemoglobin) is a measure of your average blood sugar levels over the past 2-3 months. It is expressed as a percentage and is commonly used to diagnose and monitor diabetes and prediabetes.
A1C Ranges:
- Normal: Below 5.7%
- Prediabetes: 5.7% to 6.4%
- Diabetes: 6.5% or higher
The A1C test works by measuring the percentage of hemoglobin (a protein in red blood cells) that has glucose attached to it. Since red blood cells regenerate every 3 months, the A1C test provides a long-term view of blood sugar control.
For people with diabetes, the goal is typically to maintain an A1C level below 7%, though this may vary based on individual health conditions and doctor recommendations.
