The A1C test (also known as the hemoglobin A1C or HbA1c test) measures your average blood sugar levels over the past 2 to 3 months. Here's how it works:
- Hemoglobin: A protein in red blood cells that carries oxygen.
- Glucose Attachment: When sugar enters your bloodstream, it attaches to hemoglobin.
- Measurement: The A1C test calculates the percentage of red blood cells that have glucose-coated hemoglobin.
Key Points:
- Normal Range: Below 5.7%
- Prediabetes: 5.7% to 6.4%
- Diabetes: 6.5% or above
The A1C test is a crucial tool for diagnosing and managing diabetes, as it provides a long-term view of blood sugar control.
