Blood glucose levels are assessed during fasting and two hours after taking a meal. In a normal healthy adult fasting blood glucose levels should be less than 110 mg/dl. The post prandial blood glucose levels are normally below 180 mg/dl. In case of raised blood glucose levels, glucose tolerance test
is advised for the proper diagnosis.
I hope this information has been both informative and helpful for you.
