In brief: Fasting: 70-100 mg

If have not eaten or drank anything, except for water, for an eight hour period, this fasting blood sugar level is about 70-100.
An hour after earing it may peak to about 170, and by two hours it should return to about normal fasting levels. If two or three fasting sugars are between 100-126, it is called 'impaired glucose tolerance'. If repeated FBS is over 126, it is considered type 2 diabetes.

In brief: It depends

Most labs have a reference range of 60-99 for fasting glucose (blood sugar) .
100-125 is concidered to be at increased risk of type 2 diabetes. A fasting glucose in presumed to be diabetes in certain situations. There are also ranges for non fasting sugar.
