Patient's question:

Hello, I suspect I have diabetes. What tests should I do? Thank you

Doctor's answer:

It is recommended that you go to the hospital for fasting blood glucose and glucose tolerance tests to confirm the diagnosis. The specific diagnostic criteria for diabetes are as follows:
1. Typical symptoms of diabetes + random plasma glucose concentration of ≥11.1 mmol/L.
2. Fasting plasma glucose concentration of ≥7.0 mmol/L.
3. Postprandial plasma glucose concentration of ≥11.1 mmol/L after a 2-hour oral glucose tolerance test.
Meeting any one of the above three points is sufficient for diagnosis.
