Two tests can determine whether a person is pre-diabetic:

• The Fasting Plasma Glucose (FPG) Test (100-125 mg/dL of glucose in the bloodsteam)
• Oral Glucose Tolerance (OGTT) Test (140-199 mg/dL of glucose in the bloodstream)

If your fasting blood glucose level is within the above ranges, your glucose tolerance is impaired. Make an appointment with your primary care physician to discuss strategies to reduce your blood glucose levels.

Diabetes occurs in individuals of all ages and races, but African-Americans, Latinos, Native Americans and Asian Americans/Pacific Islanders are at higher risk for developing diabetes.
