to play roles.
There are 20.8 million children and adults in the United States,
or 7% of the population, who have diabetes. While an estimated 14.6
million have been diagnosed with diabetes, unfortunately, 6.2 million
people (or nearly one-third) are unaware that they have the disease.
In order to determine whether or not a patient has pre-diabetes
or diabetes, health care providers conduct a Fasting Plasma Glucose
Test (FPG) or an Oral Glucose Tolerance Test (OGTT). Either test
can be used to diagnose pre-diabetes or diabetes. The American Diabetes
Association recommends the FPG because it is easier, faster, and
less expensive to perform.
With the FPG test, a fasting blood glucose level between 100 and
125 mg/dl signals pre-diabetes. A person with a fasting blood glucose
level of 126 mg/dl or higher has diabetes.
In the OGTT test, a person's blood glucose level is measured after
a fast and two hours after drinking a glucose-rich beverage. If
