what is ha1c

HbA1c, also known as Hemoglobin A1c or glycated hemoglobin, is a blood test that measures your average blood sugar levels over the past 2-3 months. It is commonly used to diagnose and monitor diabetes and prediabetes.

How does it work?

• 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 reflects your average blood sugar levels over that period.

A1C Ranges:

A1C Level Diagnosis

Below 5.7% Normal
5.7% - 6.4% Prediabetes
6.5% or higher Diabetes

Why is it important?

• It helps in diagnosing diabetes and prediabetes.
• It monitors how well your diabetes is being managed over time.
• It provides a more comprehensive picture of blood sugar control compared to daily glucose tests.
