The blood glucose test represents the blood glucose level in the body, the normal person’s fasting venous plasma glucose is less than 6.1mmol/L, two hours after meal venous plasma glucose is less than 7.8mmol/L, if the blood glucose is within this range, it means the glucose metabolism is normal. If the blood glucose is higher than these two values, it indicates the presence of abnormal glucose metabolism, for example, if the fasting blood glucose is between 6.1-7.0mmol/L and the two-hour postprandial blood glucose is between 7.8-11.1mmol/L, it represents pre-diabetes. Fasting blood glucose greater than or equal to 7mmol/L and two hours after meal blood glucose greater than or equal to 11.1mmol/L represents the presence of diabetes and requires prompt consultation with the endocrinology department to determine the treatment plan.
