Clinically, the normal range of fasting blood glucose is 3.9-6.0 mmol/L, and 2-hour postprandial blood glucose is normal less than 7.8 mmol/L. For diabetic patients, the goal of glycemic control is generally in the range of fasting blood glucose 4.4 mmol/L to 7.0 mmol/L, and non-fasting blood glucose is not more than 10.0 mmol/L. Fasting blood glucose and 2-hour postprandial blood glucose are often used clinically as criteria for assessing blood glucose. Fasting blood glucose 3.9-6.0mmol/L is normal, 6.1-6.9mmol/L is impaired fasting blood glucose regulation, ≥7.0mmol/L with diabetic symptoms can be diagnosed as diabetes. Postprandial 2-hour blood glucose<7.8mmol/L is normal, 7.8~11.0mmol/L is abnormal glucose tolerance, ≥11.1mmol/L with diabetic symptoms can be diagnosed as diabetes. For diabetic patients, the goal of glycemic control is generally in the fasting blood glucose 4.4mmol/L ~ 7.0mmol/L, non-fasting blood glucose does not exceed 10.0mmol/L, but also need to set up glycemic control goals according to the individual situation. For pregnant women, the normal fasting blood glucose value <5.1mmol/L, 1 hour postprandial blood glucose <10.0mmol/L, 2 hours postprandial blood glucose value <8.5mmol/L.
