According to American Diabetes Association that the Fasting Plasma Glucose (FPG) test is the preferred method for diagnosing diabetes, because it is easy to do, convenient, and less expensive than other tests. The FPG test measures blood glucose in a person who has fasted for at least 8 hours and is most reliable when given in the morning.
The test results indicate whether your blood glucose level is normal or whether you have prediabetes or diabetes:
The test results indicate whether your blood glucose level is normal or whether you have prediabetes or diabetes:
- Normal: Normal blood sugar levels measure less than 100 mg/dl (milligrams per deciliter) after the fasting glucose test.
- Prediabetes: Blood glucose levels of 100-125 mg/dl after an overnight or eight-hour fast may indicate prediabetes. People with these results are considered to have impaired fasting glucose (IFG).
- Diabetes: Diabetes is diagnosed when the blood glucose is 126 mg/dl or above.
