A 2-hour OGTT value of 11.2 mmol/L falls into which category?

A 2-hour OGTT value of 11.2 mmol/L falls into which category?

• A. Normal
• B. Impaired glucose tolerance
• C. Diabetes
• D. Borderline

Answer: (C)

Interpreting the 2-hour value after a 75 g glucose load hinges on the diagnostic thresholds for the oral glucose tolerance test. Normal response is typically below about 7.8 mmol/L. Impaired glucose tolerance (a prediabetes category) ranges from roughly 7.8 to 11.0 mmol/L. Diabetes is diagnosed when the 2-hour value is at or above 11.1 mmol/L. This value of 11.2 mmol/L is just over that diabetes threshold, which equates to about 202 mg/dL, so it meets the criterion for diabetes under OGTT interpretation.
