This table shows the criteria used by health care professionals to diagnose pre-diabetes as either impaired fasting glucose (IFG) or impaired glucose tolerance (IGT).
The Fasting Plasma Glucose Test (FPG) measures a person’s blood glucose after an overnight fast (8 to 12 hours).
The 2-Hour Glucose Challenge is performed after an overnight 8 to 12 hour fast and measures a person’s plasma 2 hours after drinking a 75-gram glucose solution.
