Morning blood glucose generally refers to fasting blood glucose, fasting blood glucose 6.5mmol/L is not necessarily diabetes.
The diagnostic criteria for diabetes are a fasting blood glucose greater than 7mmol/L or a two-hour postprandial blood glucose greater than 11.1mmol/L.
A fasting blood glucose of 6.5 mmol/L is above the normal blood glucose range (i.e., 3.9 to 6.1 mmol/L) but does not meet the diagnostic criteria for diabetes mellitus (fasting blood glucose greater than or equal to 7 mmol/L). Therefore, a fasting blood glucose of 6.5 mmol/L is not necessarily diabetes.
In addition, fingertip blood is capillary blood, which can not be used as the basis for diabetes diagnosis, but only for our daily monitoring. Therefore, if you want to make a clear diagnosis, you can improve the oral glucose tolerance test, if the fasting blood glucose after the test is greater than 7mmol/L or two hours after the meal blood glucose is greater than 11.1mmol/L, you need to consider whether diabetes occurs.
If the fasting blood glucose value is abnormal, it is recommended to go to the endocrinology department of the hospital for further consultation.
