What is the normal range for HbA1c levels?

For individuals without diabetes, the normal HbA1c range is typically between 4% and 5.6%. A result within this range indicates that blood sugar levels have been well-regulated over the past 2-3 months. If HbA1c levels are between 5.7% and 6.4%, this may indicate prediabetes, meaning blood sugar levels are higher than normal but not yet high enough to be diagnosed as diabetes. An HbA1c result of 6.5% or higher is used to diagnose diabetes. Keeping HbA1c levels within the normal range is important for maintaining good overall health and preventing the onset of diabetes.
