What 2-hour OGTT value is considered normal?

What 2-hour OGTT value is considered normal?

• A. <6.0 mmol/L
• B. <6.5 mmol/L
• C. 8.0 mmol/L
• D. <7.8 mmol/L

Answer: (D)

Understanding the 2-hour OGTT value involves how well the body clears glucose after a glucose load. The standard threshold for normal glucose tolerance is a 2-hour plasma glucose below 7.8 mmol/L. Values from 7.8 up to about 11.0 mmol/L indicate impaired glucose tolerance (a prediabetic state), and 11.1 mmol/L or higher points to diabetes. So the normal 2-hour value is anything less than 7.8 mmol/L. An 8.0 mmol/L reading would exceed the normal cutoff, while the other options (<6.0 or <6.5) are not the conventional normal threshold used in this interpretation.
