Any of the following:
Symptoms of diabetes (polyuria,
polydipsia, unexplained weight loss) plus a casual plasma glucose
A fasting plasma glucose concentration > 126 mg/dL (measured after at least 8 hours of no caloric intake)
An abnormal oral glucose tolerance test result (a plasma glucose concentration 200 mg/dL 2 hours after a glucose load of 75 grams of anhydrous glucose dissolved in water).
Consider testing all persons age 45 and older (if normal,
repeat every 3 years)
Consider testing at a younger age, or more frequently, for any of the following:
First-degree relatives of persons with diabetes
Members of high-risk ethnic groups (eg, African American, Hispanic, Native American)
Mothers of babies weighing>9 lb at birth
Women with a history of gestational diabetes
Hypertensive patients ( 140/90 mm Hg)
Dyslipidemic patients (HDL cholesterol 35 mgldL or triglyceride 250 mgldL or both)
Patients with previous
findings of impaired glucose tolerance:
Not recommended for routine clinical use.
In the absence of
unequivocal hyperglycemia with acute metabolic decompensation, these
criteria should be confirmed by repeat testing on another day.
