A blood glucose of 7.35 mmol/L needs to be distinguished from a fasting blood glucose, a two-hour postprandial blood glucose, or a random blood glucose. If the fasting blood sugar 7.35mmol / L, combined with the typical “three more and one less” symptoms of diabetes, the diagnostic criteria for diabetes. The diagnostic criteria for diabetes mellitus are the typical “three more and one less” symptoms (excessive drinking, excessive urination, excessive eating, and weight loss) combined with a venous plasma glucose ≥11.1mmol/L or fasting glucose ≥7.0mmol/L at any time of the day, or a glucose of ≥11.1mmol/L at 2 hours after a glucose tolerance test. A diagnosis of diabetes is made when one is met. Just once even a fasting blood glucose of 7.35 mmol/L is not enough to diagnose diabetes. This is due to the fact that the body can experience a transient increase in blood glucose during many times of stress, such as in cases of fever, infection, surgery, etc., where high blood glucose tends to occur. This is a time when we cannot rely on a single blood sugar alone as a diagnostic criterion. It is recommended that people who notice abnormal blood glucose levels should seek medical attention in time.
