What fasting glucose level indicates diabetes on two separate tests?

• A. 126 mg/dL or higher on two separate tests
• B. 100-125 mg/dL considered normal
• C. 85 mg/dL ideal
• D. 90 mg/dL normal

Answer: (A)

Fasting glucose is used to diagnose diabetes by looking for persistent hyperglycemia rather than a single high reading. If the fasting value remains elevated on two separate occasions, it confirms diabetes. Repeating the test helps ensure the finding isn’t a temporary spike caused by illness, stress, or a momentary lapse in fasting. The other ideas describe normal or ideal ranges or rely on just one elevated result, which cannot establish a diabetes diagnosis. So the key point is that two elevated fasting glucose measurements on separate occasions indicate diabetes.
