Which fasting glucose range defines prediabetes?

Which fasting glucose range defines prediabetes?

• A. 70-99 mg/dL
• B. 100-125 mg/dL
• C. 126-139 mg/dL
• D. 140-199 mg/dL

Answer: (B)

The main idea is how fasting glucose levels categorize glycemic status. After an 8-hour fast, a fasting plasma glucose (FPG) result of 100-125 mg/dL is called impaired fasting glucose, which is the category for prediabetes. Values below 100 mg/dL are considered normal, while a result of 126 mg/dL or higher on separate tests indicates diabetes. So, the range 100-125 mg/dL best defines prediabetes because it sits between normal and diabetic thresholds. The lower ranges (70-99) are normal, and the higher ranges (126-139, 140-199) are in the diabetes territory for fasting glucose.
