No, blood glucose and A1C are not the same, but they are related. Here’s how they differ:

  • Blood Glucose: This measures the amount of sugar (glucose) in your blood at a specific moment. It can fluctuate throughout the day based on food, exercise, and other factors.

  • A1C (Hemoglobin A1C): This test measures your average blood glucose levels over the past 2-3 months. It reflects the percentage of hemoglobin in your red blood cells that has glucose attached to it.

Aspect Blood Glucose A1C

Measurement Instant snapshot 2-3 month average
Units mg/dL or mmol/L Percentage (%)
Purpose Daily monitoring Long-term diabetes management

While blood glucose gives you immediate feedback, A1C provides a broader picture of your blood sugar control over time. Both are important for managing diabetes effectively.
