A1C vs. Glucose: What's the Difference?
-
A1C Test:
- Measures your average blood sugar levels over the past 2-3 months.
- Reflects the percentage of hemoglobin in your red blood cells that has glucose attached to it.
- Used to diagnose prediabetes and diabetes, and to monitor long-term blood sugar control.
- Reported as a percentage (e.g., 5.7% for prediabetes, 6.5% or higher for diabetes).
-
Glucose Test:
- Measures your current blood sugar level at a single point in time.
- Often done through a finger prick or blood draw.
- Used for daily monitoring of blood sugar, especially for people with diabetes.
- Reported in mg/dL (e.g., 126 mg/dL or higher indicates diabetes).
Key Differences:
Aspect A1C Glucose
Time Frame 2-3 months Current moment
Purpose Long-term monitoring/diagnosis Immediate blood sugar levels
Measurement Percentage (%) mg/dL
Both tests are important for managing diabetes, but they serve different purposes. A1C provides a broader picture of blood sugar control, while glucose tests offer real-time insights.
