2. When hypoglycemia often occurs recently, it is best to monitor pre meal blood glucose and night blood glucose; When blood glucose is often high in the near future, fasting and 2-hour postprandial blood glucose should be monitored to more accurately reflect the degree of elevated blood glucose.
3. It is better to monitor blood glucose at different times of a day than at the same time of a day. Because the former is easier to reflect the change rule of blood glucose in 24 hours a day. If blood glucose is measured at the same time every day, it is always unknown how to control blood glucose levels at other times of the day.
Blood glucose refers to the glucose contained in blood. Blood glucose measurement is the main indicator to judge the condition and control of diabetes The normal value of venous plasma was 3.6 ~ 6.1 mmol / L (65 ~ 110 mg / dl).
