what is hb1ac

HbA1c, or Hemoglobin A1c, 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 and monitor diabetes and prediabetes.

How Does HbA1c Work?

• Glucose in your blood attaches to hemoglobin, a protein in red blood cells.
• The HbA1c test measures the percentage of hemoglobin that is coated with sugar.
• Since red blood cells regenerate every 3 months, the test reflects your average blood sugar levels over that period.

HbA1c Ranges:

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

Why is HbA1c Important?

• It provides a long-term view of blood sugar control.
• It helps in managing diabetes and reducing the risk of complications.
