what is mean glucose level

Mean glucose level refers to the average blood sugar level over a specific period, typically measured over 2-3 months using the A1C test. The A1C test provides an average by measuring the percentage of hemoglobin in your red blood cells that is coated with glucose. Here’s a breakdown of what the results mean:

A1C % Mean Glucose Level (mg/dL) Condition

Below 5.7 Below 117 Normal
5.7–6.4 117–137 Prediabetes
6.5 or above 140 or above Diabetes

• Normal: Below 5.7% (below 117 mg/dL)
• Prediabetes: 5.7% to 6.4% (117–137 mg/dL)
• Diabetes: 6.5% or above (140 mg/dL or above)

This test is crucial for diagnosing and managing diabetes or prediabetes, as it reflects long-term blood sugar control rather than a single moment in time.
