What is considered a normal A1C level?

A normal A1C level is defined as less than 5.7%. This measurement indicates that an individual has average blood glucose levels within the normal range and is not at an increased risk for diabetes. A1C is a blood test that reflects the average level of blood sugar over the previous two to three months.

When understanding the context of other A1C categories, levels equal to or greater than 5.7% but less than 6.5% suggest prediabetes, which indicates a heightened risk and the need for monitoring and potential lifestyle changes. An A1C level of 6.5% or higher is indicative of diabetes. Therefore, being under 5.7% signifies healthy blood sugar control and a lower risk for metabolic disorders.
