Pre-Diabetes
Alternate Names : Impaired Glucose Tolerance, Impaired Fasting Glucose, IGT, IFG
How is the condition diagnosed?
There are two different tests that doctors use to screen for
pre-diabetes. Either one is acceptable.
Fasting plasma glucose test, also called FPG. With this test, a person's
blood glucose level is measured following a fast, which means no food or
drink has been taken in for at least 8 hours. If the blood glucose level is between
110 and 125 mg/dL, the person has pre-diabetes. Levels higher than that indicate
type 2 diabetes.
Oral glucose tolerance test, also called OGTT. With this test, a person's
blood glucose level is measured after a fast and 2 hours after drinking a special
glucose drink. If the 2-hour blood glucose level is 140 to 199 mg/dL, the person
has pre-diabetes. Levels at 200 mg/dL or higher indicate type 2 diabetes.
