what is mean blood glucose

Mean blood glucose (MBG) refers to the average blood sugar level over a specific period, typically measured over several weeks or months. It is often estimated using the A1C test, which reflects your average blood glucose levels over the past 2-3 months.

Here’s a quick reference for A1C and estimated average glucose (eAG):

A1C (%) eAG (mg/dL)

6 126
7 154
8 183
9 212
10 240

• Normal: Below 5.7% A1C
• Prediabetes: 5.7% to 6.4% A1C
• Diabetes: 6.5% or higher A1C

Monitoring your mean blood glucose helps in managing diabetes and reducing the risk of complications.
