Whether it is fasting blood glucose, 2-hour postprandial blood glucose, random blood glucose, biochemical examination of glucose 5.16mmol / L are within the normal range, generally do not need treatment. Glucose in biochemical examination generally refers to the concentration of blood glucose, fasting blood glucose normal value of 3.9~6.1mmol/L, 2 hours after meal blood glucose normal value should be less than 7.8mmol/L, random blood glucose normal value should be less than 11.1mmol/L, so biochemical examination of glucose 5.16mmol/L is within the normal range, so there is no need for treatment in general. If there is still a suspicion of abnormal blood glucose, it is recommended to improve the glycated hemoglobin, glucose tolerance test and other tests to determine whether there is an abnormal blood glucose value. If the blood glucose value is high, it is recommended to go to the hospital for consultation and standardized treatment under the guidance of the doctor.
