Normal fasting glucose should be between 70-110 mg/dl. Your blood sugar level tells you how much sugar is in your blood. A fasting glucose test looks at your blood sugar when you wake up in the morning before you have eaten anything.
Blood sugars generally rise after we eat, and that rise usually spikes about 2 hours after a meal (in medical terms they say "postprandial" meaning after a meal). Postprandial blood sugars should stay under 140mg/dl.
There are a few ways to determine if a person has diabetes. If a person has repeated fasting glucose levels higher than 126 mg/dl, they are probably diabetic.
A glucose tolerance test may indicate either impaired glucose tolerance or diabetes. This is a test where you drink a sugar solution and have your blood sugars checked every half hour for 2-3 hours. In a person with impaired glucose tolerance (IR or pre-diabetes), blood sugars would go up to between 140-200mg/dl (7.8 mmol/L-11.1 mmol/L). In a diabetic, blood sugars would exceed 200mg/dl (11.1 mmol/L).
Lastly, a blood test that looks at hemoglobin A1C may be helpful in diagnosing diabetes although it should be used more for monitoring the treatment of diabetes patients.
Obviously the more tests that are high, the more likely the person being tested has diabetes.
