A random blood glucose of 6.7 mmol/L is normal. If it is necessary to clarify the presence of elevated blood glucose, it is recommended that intravenous fasting blood glucose and two-hour postprandial blood glucose measurements be performed under the supervision of a physician. In general, the normal fasting blood glucose of normal people is between 3.9 and 6.1mmol/L, 2-hour postprandial blood glucose should be less than 7.8mmol/L, and the normal value of random blood glucose should be less than 11.1mmol/L. Therefore, random blood glucose of 6.7mmol/L is normal. If you want to know whether there is hyperglycemia, postprandial blood glucose and fasting blood glucose measurements are recommended, and it is recommended that you go to a regular hospital for examination.
