What is the standard range of blood sugar levels
The current diagnostic criteria for diabetes is the World Health Organization 1999 recommendation criteria: typical symptoms, polydipsia, polyuria and weight loss. Fasting blood glucose ≥ 7.0 mmol/l or postprandial blood glucose ≥ 11.1 mmol/l. Diabetes can be diagnosed. If there are no typical symptoms, only fasting blood glucose ≥ 7.0 mmol/l or postprandial blood glucose ≥ 11.1 mmol/l. Repeat once, and those who still reach the above value or those whose 2-hour blood glucose is ≥11.1 mmol/l. in addition to the glucose tolerance test can be diagnosed with diabetes.
The latest foreign standard (this is the most stringent standard) is Fasting is lower than 5.6, and after meals is lower than 7.8, which is commonly known as the 5678 method. With typical symptoms, based on the venous blood glucose level, fasting blood glucose of 3126 mg/dl (7.0 mmol/l) or postprandial blood glucose of ≥200 mg/dl (11.1 mmol/l) can confirm the diagnosis of diabetes.
If there are no typical symptoms, only fasting blood glucose of 3126 mg/dl (7.0 mmol/l) or postprandial blood glucose of 3200 mg/dl should be repeated again. A 2-hour blood glucose level of 3200 mg/dl (11.1 mmol/l) can be diagnosed as diabetes. If the above results are unclear, an oral glucose tolerance test (OGTT) should be performed. If the 2-hour OGTT blood glucose is between 140 and 200 mg/dl (7.8 to 11.1 mmol/l), it is impaired glucose tolerance; if the fasting blood glucose is 110 to 126 mg/dl (6.1 to 7.0 mmol/l), it is impaired fasting blood glucose. , were not diagnosed with diabetes.
If the random blood sugar is greater than or equal to 11.1 mmol/L, diabetes can be diagnosed. (It needs to be confirmed again on another day, excluding stress states, such as infection, trauma) If the fasting blood sugar is greater than or equal to 7.0 mmol/L twice, it can be confirmed. Diabetes is diagnosed. (It needs to be confirmed again on another day, excluding stress states, such as infection, trauma). The normal fasting blood glucose is 3.89-6.1 mmol/L, and the normal blood glucose 2 hours after meals is less than 7.8 mmol/L. Hourly blood sugar is greater than or equal to 7.8mmol/L, and less than 11.1mmol/L, indicating impaired glucose tolerance. 2 hours postprandial blood sugar is greater than or equal to 11.1mmol/L, which is considered as diabetes (need to try again on another day). (Except stress state) , such as infection, trauma). At this time, regular treatment is necessary.
