At one hour, your test falls into the normal, non-diabetic range if your blood glucose remains below 200 mg/dL. Two hours after your meal, blood glucose should remain below 140 mg/dL. A level of over 200 mg/dL at two hours post-prandial -- which means after a meal -- indicates diabetes.
Diabetics experience larger spikes in blood glucose that take longer to return to baseline. For diabetics, blood glucose an hour after eating should remain below 180 mg/dL or no more than 80 mg/dL over your pre-meal levels. The highest spikes in blood glucose levels often occur after breakfast. If you experience hypoglycemia, or low blood glucose levels before a meal, you might experience a higher-than-normal spike over baseline levels; this doesn't necessarily indicate an abnormal rise.
