At what A1C level is an individual classified as having prediabetes?

An individual is classified as having prediabetes when their A1C level falls between 5.7% and 6.4%. This range indicates that blood glucose levels are higher than normal but not yet high enough to be classified as diabetes. The A1C test measures the average blood sugar levels over the past two to three months, and the specific cutoff points for diagnosing prediabetes and diabetes are based on research that has established these thresholds. Maintaining an A1C within this range is important as it signifies potential metabolic issues that could lead to type 2 diabetes if lifestyle changes are not made.

In this context, the other options reflect different classifications. A level below 5.7% is considered normal, levels above 6.5% indicate diabetes, and an A1C above 12% is often seen in severe cases of diabetes with poor management. Understanding these classifications is crucial for early intervention and management of blood sugar levels.
