Which 2-hour OGTT range defines impaired glucose tolerance?

Which 2-hour OGTT range defines impaired glucose tolerance?

• A. 6.0-7.5 mmol/L
• B. 5.0-6.8 mmol/L
• C. 7.8-11.0 mmol/L
• D. 11.1-12.5 mmol/L

Answer: (C)

Impaired glucose tolerance is determined by the 2-hour value after a 75 g oral glucose load. If the 2-hour plasma glucose falls between 7.8 and 11.0 mmol/L, that range defines impaired glucose tolerance. Values below 7.8 mmol/L are considered normal, while 11.1 mmol/L or higher indicates diabetes. In mg/dL, impaired glucose tolerance corresponds to about 140–199 mg/dL. This range shows the body isn’t handling glucose as well as normal, signaling increased risk for progression to type 2 diabetes and cardiovascular issues, and it often prompts lifestyle or treatment interventions.
