Blood glucose indicators commonly monitored in clinical practice include fasting blood glucose and 2-hour postprandial blood glucose, with the latest normal standard for fasting blood glucose being 3.9-6.1 mmol/L and 2-hour postprandial blood glucose <7.8 mmol/L. Fasting blood glucose refers to the blood glucose value obtained by blood sampling without eating any food for at least 8 hours. The 2-hour postprandial blood glucose is the blood glucose value measured 2 hours after the first bite of food. The blood glucose values from these two tests are in the normal standard range, indicating that the body's ability to regulate blood glucose concentration is normal. If a patient finds that his/her blood glucose exceeds or falls below the normal blood glucose range, he/she should consult a doctor in time to complete the relevant examinations and carry out treatment under the doctor's guidance.
