The A1C level, also known as HbA1c or glycated hemoglobin, is a measure of your average blood sugar levels over the past 2 to 3 months. It is expressed as a percentage and is used to diagnose and monitor diabetes and prediabetes.
A1C Ranges:
- Normal: Below 5.7%
- Prediabetes: 5.7% to 6.4%
- Diabetes: 6.5% or above
How It Works:
- Glucose in your blood attaches to hemoglobin, a protein in red blood cells.
- The A1C test measures the percentage of red blood cells that have glucose-coated hemoglobin.
- Since red blood cells regenerate every 3 months, the A1C test reflects your average blood sugar levels over that period.
Why It Matters:
- It helps diagnose diabetes and prediabetes.
- It monitors how well your diabetes treatment plan is working.
- Higher A1C levels are linked to an increased risk of diabetes complications.
