Which A1C range defines prediabetes?

Explanation:
A1C shows the average blood glucose over about the past 2 to 3 months, which is why fixed thresholds help categorize glycemic status. Normal is below 5.7%, prediabetes is from 5.7% up to 6.4%, and diabetes is diagnosed at 6.5% or higher. So the range 5.7% to 6.4% defines prediabetes, indicating higher-than-normal glucose but not enough to meet diabetes criteria. Values above 6.5% are considered diabetes, while below 5.7% is normal.
