Human glucose parameters here should refer to the human blood sugar parameters, whether fasting blood sugar or 2 hours after meal blood sugar, blood sugar 8.7mmol / L are abnormal, if it is random blood sugar 8.7mmol / L, is normal. The normal value of fasting blood glucose is 3.9~6.1mmol/L, and the two-hour postprandial blood glucose should be less than 7.8mmol/L. Either the fasting blood glucose or the two-hour postprandial blood glucose of 8.7mmol/L is already higher than the normal range, and it is not normal. The normal value of random blood glucose is in less than or equal to 11.1 mmol/L, while blood glucose 8.7 mmol/L is in the normal range. Before blood is drawn for glucose measurement, fasting blood glucose requires no food or water for at least 8 hours before the blood is drawn, and the start of the 2-hour postprandial blood glucose recording is based on the time of the first bite of the meal. If the phenomenon of blood glucose 8.7mmol/L occurs, you need to clarify when the blood glucose is before judging whether it is normal or not, if it is abnormal blood glucose, it is recommended to go to the hospital in time.
