The A1C level indicating prediabetes falls within the range of 5.7% to 6.4%. This classification is essential for identifying individuals at increased risk of developing type 2 diabetes. The American Diabetes Association defines these thresholds based on research demonstrating that individuals with A1C levels in this range have a higher probability of progressing to diabetes if no interventions are taken.

The rationale behind using A1C as a diagnostic tool is that it provides an average of glucose levels over a two to three-month period, reflecting long-term glycemic control. Levels below 5.7% are considered normal, while levels of 6.5% or higher indicate diabetes. Therefore, the correct range for prediabetes is critical for timely interventions aimed at lifestyle modifications and risk reduction. Identifying individuals with these A1C levels enables healthcare providers to implement preventative strategies to reduce the likelihood of progression to diabetes and associated complications.
