The fasting blood glucose test is the test most commonly used to diagnose diabetes. It measures blood glucose levels after a period of fasting, usually at least eight hours without food or liquid (except water).f the first level is above 125 mg/dL, the fasting blood glucose test will be done again (for example, the next day) to confirm a diagnosis of diabetes. A value between 100 and 125 mg/dL indicates pre-diabetes.
