The A1C blood test, also known as the hemoglobin A1C or HbA1c test, is a common blood test used to measure your average blood sugar (glucose) levels over the past 2 to 3 months. It is primarily used to:
- Diagnose prediabetes and diabetes
- Monitor blood sugar control in people with diabetes
The test works by measuring the percentage of hemoglobin (a protein in red blood cells) that is coated with sugar. Since red blood cells regenerate every 3 months, the A1C test provides a long-term view of blood sugar levels.
A1C Results and What They Mean:
A1C Level (%) Diagnosis
Below 5.7 Normal
5.7 - 6.4 Prediabetes
6.5 or higher Diabetes
For people with diabetes, the goal is typically to keep their A1C level below 7%, though this may vary based on individual health conditions.
Key Points:
- No fasting is required for the A1C test.
- It is a simple blood draw, usually from the arm or finger.
- The test is not affected by short-term fluctuations in blood sugar.
