what is ac1 diabetes

The A1C test (also known as the hemoglobin A1C or HbA1c test) is a blood test used to diagnose and monitor diabetes and prediabetes. It measures your average blood sugar levels over the past 2-3 months by assessing the percentage of hemoglobin in your red blood cells that is coated with sugar (glycated hemoglobin).

Key Points:

• Normal A1C: Below 5.7%
• Prediabetes: 5.7% to 6.4%
• Diabetes: 6.5% or higher

The A1C test is a crucial tool for managing diabetes, as it helps track how well your blood sugar is controlled over time. It is often used alongside daily blood sugar monitoring to provide a comprehensive picture of your glucose levels.
