The 3-hour postprandial blood glucose value of 9.2mmol/L is not a routine blood glucose monitoring value to determine whether treatment is needed, and it is recommended to measure fasting blood glucose and 2-hour postprandial blood glucose.
A 3-hour postprandial blood glucose of 10 mmol/L may be abnormal, and normally the 3-hour postprandial blood glucose level will return to the fasting blood glucose level, i.e. 3.9~6.1 mmol/L. However, the 3-hour postprandial blood glucose is not used as a diagnostic criterion for diabetes mellitus, and it is mostly recognized as a random glucose, which is below 11.1 mmol/L for a normal person.
According to the fasting blood glucose standard, 3-hour postprandial blood glucose 9.2mmol/L is elevated, but according to the random blood glucose, 3-hour postprandial blood glucose 9.2mmol/L is normal. It is recommended to monitor blood glucose correctly. If fasting blood glucose ≥ 7.0 mmol/L, or 2-hour postprandial blood glucose ≥ 11.1 mmol/L, or random blood glucose ≥ 11.1 mmol/L, timely medical treatment is needed.
A three-hour postprandial blood glucose value of 9.2 mmol/L is recommended to go to the hospital for further clarification under the guidance of a doctor.
