What is the blood sugar index?

After the blood sugar test results come out, there will generally be a value for the blood sugar content. This value will have a reference range. For example, the fasting whole blood sugar level is generally between 3.9 and 6.1. If it is higher or lower than this value, you must be vigilant and then compare it downwards. For more detailed advice, it is recommended to go to the department where you received treatment for a reexamination.

Normal fasting blood glucose (FBG)

① Generally, the fasting whole blood glucose level is 3.9-6.1 mmol/L (70-110 mg/dL), and the plasma glucose level is 3.9-6.9 mmol/L (70-125 mg/dL).

② Fasting whole blood glucose ≥6.7 mmol/L (120 mg/dL) and plasma glucose ≥7.8 mmol/L (140 mg/dL), repeated measurements twice can be diagnosed as diabetes.

③ When the fasting whole blood glucose is above 5.6 mmol/L (100 mg/dL) and the plasma glucose is above 6.4 mmol/L (115 mg/dL), a glucose tolerance test should be performed.

④ When fasting whole blood glucose exceeds 11.1 mmol/L (200 mg/dL), it means that insulin secretion is very little or lacking. Therefore, when fasting blood sugar is significantly elevated, diabetes can be diagnosed without the need for other tests.

Normal blood sugar level after meal

① 1 hour after meal: blood sugar 6.7-9.4 mmol/L. The maximum value is no more than 11.1mmol/L (200mg/dl)

② 2 hours after meal: blood sugar ≤7.8 mmol/L.

③3 hours after meal: Return to normal after the third hour, and all urine sugar levels are negative
