The HbA1c blood test, also known as the hemoglobin A1c test, measures your average blood sugar (glucose) levels over the past 2 to 3 months. It is commonly used to diagnose and monitor diabetes and prediabetes.
How It Works:
- Glucose in your blood attaches to hemoglobin, a protein in red blood cells.
- The test measures the percentage of hemoglobin that is coated with sugar (glycated hemoglobin).
- Since red blood cells regenerate every 3 months, the test reflects your average blood sugar levels over that period.
Key Ranges:
- Normal: Below 5.7%
- Prediabetes: 5.7% to 6.4%
- Diabetes: 6.5% or higher
Why It’s Important:
- It helps diagnose diabetes and prediabetes.
- It monitors how well your diabetes management plan is working.
- It provides a long-term view of blood sugar control, unlike daily glucose checks.
