What fasting blood sugar result is in the diabetes range?

126 mg/dL or higher on a fasting test.

  1. 126 mg/dL or higher ✔
  2. 100 mg/dL or higher
  3. 90 mg/dL or higher

Why: On a fasting test, 126 mg/dL or higher points to diabetes, 100 to 125 is prediabetes, and under 100 is normal. Fasting means nothing but water for at least 8 hours.

Huh, didn't know that: The fasting test is usually done first thing in the morning, before breakfast.
