How do I know if I have pre-diabetes?

Doctors can use either the fasting plasma glucose test (FPG) or the oral glucose tolerance test (OGTT) to detect pre-diabetes. Both require a person to fast overnight. In the FPG test, a person's blood glucose is measured first thing in the morning before eating. In the OGTT, a person's blood glucose is checked after fasting and again 2 hours after drinking a glucose-rich drink.
