Fasting blood sugar 6.6, normal?

Normal fasting blood glucose should be between 3.9 and 6.1mmol/L. Your current blood glucose value has exceeded the standard value. It is recommended to test again two hours after meals. If the blood glucose value after the test is within 7.8mmol/L, there is no need to worry too much. If it exceeds this range, you should be alert to hyperglycemia, diabetes and other diseases.
