what does hgb a1c mean

Hgb A1C, also known as Hemoglobin A1C or HbA1c, 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.

Here’s how it works:

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

A1C Ranges:

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

This test is a key tool in managing diabetes and assessing the risk of complications.
