What HbA1c range indicates prediabetes?

What HbA1c range indicates prediabetes?

• A. 5.3-5.6%
• B. 5.7-6.4%
• C. 6.5-7.0%
• D. 6.0-6.4%

Answer: (B)

HbA1c reflects the average blood glucose over the past two to three months by measuring how much glucose has attached to hemoglobin in red blood cells. Clinically, it’s used to categorize glycemic status into normal, prediabetes, and diabetes. Values below 5.7% are considered normal, 5.7% to 6.4% define prediabetes, and 6.5% or higher on repeated testing typically indicates diabetes. The range 5.7% to 6.4% best identifies individuals at increased risk who haven’t yet reached diabetes, highlighting a window where lifestyle changes can significantly reduce progression risk. Keep in mind that HbA1c can be influenced by factors like anemia or hemoglobin variants, so results are interpreted in the broader clinical context.
