Normal sugar blood level?

100mg/dL or less: Physicians measure patient's fasting blood glucose. This is the blood sugar taken when the patient hasn't had food or drink for at least 8 hours. "normal" is considered to be 100mg/dl or less. There is a little leeway before a level is high enough to raise concern and necessitate intervention though. A non-fasting blood sugar - or random should be less than 150... Especially 2 hours after you eat.

70-99mg/dl: Normal fasting glucose levels are about 70-99mg/dl. Levels between 100 and 126 represent pre-diabetes. If you fasting levels are higher than 126, that is diagnostic of diabetes.

Normal Blood Sugar: Less than 100 mg./dL fasting, and less than 140 mg./dL 2 hours after eating. Also A1c is less than 6.5%.
