what's a hemoglobin a1c test

The Hemoglobin A1C (HbA1c) test is a blood test that measures your average blood sugar (glucose) levels over the past 2 to 3 months. It is commonly used to diagnose prediabetes and diabetes, as well as to monitor how well you are managing your diabetes over time.

How It Works:

• Glucose in your blood attaches to hemoglobin, a protein in red blood cells.
• The A1C test measures the percentage of your red blood cells that have glucose-coated hemoglobin.
• Since red blood cells regenerate every 3 months, the test provides a long-term view of your blood sugar levels.

A1C Results:

• Normal: Below 5.7%
• Prediabetes: 5.7% to 6.4%
• Diabetes: 6.5% or above

Why It's Important:

• It helps in diagnosing diabetes and prediabetes.
• It provides a broader picture of blood sugar control compared to daily glucose tests.
• It is a key tool for managing diabetes and reducing the risk of complications.
