Normal A1C range?

Normal A1C range?

• A. 4.0-5.0%
• B. 6.5-7.5%
• C. 5.7-6.5%
• D. 7.0-7.5%

Answer: (C)

Understanding A1C involves dividing glycemic status into normal, prediabetes, and diabetes based on percentage ranges. Normal is typically defined as below 5.7%. Prediabetes usually falls in about 5.7% to 6.4%, and diabetes is diagnosed at 6.5% or higher. Among the given options, the range beginning at 5.7% and extending to around 6.5% best captures the boundary where normal becomes elevated risk, making it the most appropriate choice in this set. The other ranges are either entirely within normal (4.0-5.0%) or clearly in the diabetes range (6.5-7.5% and 7.0-7.5%).
