What A1C level is classified as prediabetes?

The A1C test measures the average blood sugar levels over the past two to three months and is a common tool used for diagnosing diabetes and prediabetes. A result in the range of 5.7% to 6.4% indicates prediabetes. This classification suggests that the person's blood sugar levels are higher than normal but not high enough yet to be diagnosed as diabetes.

Individuals within this range are at an increased risk of developing type 2 diabetes and experiencing other metabolic conditions. Early detection through the A1C test allows for intervention strategies that can help manage blood sugar levels and potentially prevent progression to full-blown diabetes.

In contrast, other ranges indicate different health classifications. For example, an A1C level below 5.7% is considered normal, while levels of 6.5% or higher are diagnostic for diabetes. An A1C level at 7.1% or higher confirms established diabetes and requires more comprehensive management strategies due to the elevated risk associated with prolonged high blood sugar levels.
