fasting plasma glucose test

Explanation:

The "fasting plasma glucose test" (FPG) is a diagnostic test being used to know whether people have diabetes, a condition of having high levels of sugar in the blood. This is being done by letting the patient fast for at least 8 hours. This will check the level of fasting blood sugar. If the level is greater than 126 mg/dL, then the person has a positive result. In order to confirm, another test will be done on the following day in the morning.
