The A1C test, also known as the hemoglobin A1C or HbA1c test, is a blood test used to measure the average blood sugar (glucose) levels over the past 2 to 3 months. It is a key tool for diagnosing and managing diabetes and prediabetes.
How Does the A1C Test Work?
- The test measures the percentage of hemoglobin (a protein in red blood cells) that is coated with sugar (glycated hemoglobin).
- Red blood cells regenerate every 3 months, so the A1C test reflects long-term blood sugar control.
A1C Ranges for Diabetes and Prediabetes:
A1C Level (%) Diagnosis
Below 5.7 Normal
5.7 - 6.4 Prediabetes
6.5 or higher Diabetes
Why Is A1C Important for Diabetics?
- It helps monitor how well diabetes is being managed.
- The goal for most diabetics is to maintain an A1C level below 7%, though individual targets may vary based on health conditions.
