What is the range of diabetes values?

The diagnostic range of diabetes is fasting blood glucose ≥7.0mmol/L or 2 hours postprandial blood glucose ≥11.1mmol/L or random blood glucose ≥11.1mmol/L.

Fasting blood glucose refers to blood glucose after not eating for at least 8 hours. When fasting blood glucose reaches or exceeds 7.0mmol/L, it is necessary to be highly alert to the possibility of diabetes. 2 hours postprandial blood glucose is generally measured from the first meal, and this value ≥11.1mmol/L is abnormal. Random blood glucose refers to blood glucose at any time regardless of meal time. When random blood glucose ≥11.1mmol/L, combined with clinical symptoms, such as polydipsia, polyuria, weight loss, etc., diabetes can be diagnosed.

It should be noted that diabetes cannot be diagnosed only by one abnormal blood glucose test result. Usually, multiple measurements or other related tests, such as glycosylated hemoglobin test, are needed to confirm the diagnosis. At the same time, for people with high risk factors such as blood sugar at critical values or family history of diabetes, blood sugar should be monitored regularly to detect abnormal blood sugar early and intervene in time. In addition, diagnosis of diabetes also requires comprehensive consideration of symptoms, medical history, physical condition and other factors. It is recommended to diagnose and treat under the guidance of a professional doctor.
