1. Fasting blood glucose: It mainly reflects the blood glucose level in the basal state (8-10 hours after the last meal) when there is no diet load, which is an important basis for the diagnosis of diabetes.
2. Blood glucose 2 hours after a meal: an important indicator reflecting the reserve function of pancreatic islet B cells, that is, the ability of food to stimulate B cells to secrete insulin after eating. Measuring blood glucose 2 hours after a meal can reveal possible postprandial hyperglycemia, which can better reflect whether eating and using hypoglycemic drugs are appropriate, which is not reflected by fasting blood glucose.
3. Blood glucose before going to bed reflects the ability of pancreatic B cells to control hyperglycemia after eating dinner. It is the basis for guiding night medication or insulin dosage.
4. Random blood glucose: It is possible to understand the effect of the body on blood sugar under special circumstances, such as the amount of meals, drinking, fatigue, illness, mood changes, menstrual periods, etc.
