The A1C test and glucose tests measure different aspects of blood sugar levels:
-
A1C Test:
- Measures the 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 levels, especially in people with diabetes.
- Reported in mg/dL (e.g., 126 mg/dL or higher indicates diabetes).
In summary, the A1C test provides a long-term view of blood sugar control, while glucose tests give a snapshot of your blood sugar at a specific moment.
