Diabetes Risk Testing


Diabetes Risk Testing

There are an estimated 84 million adults 18 years and older in the U.S. who are pre-diabetic or at risk for developing diabetes and another 7 million with undiagnosed diabetes.1

Recommendations by the American College of Obstetricians and Gynecologists2 state testing for type 2 diabetes risk in asymptomatic people should be considered:

  • Adults of any age who are overweight or obese and who have one or more additional risk factors for diabetes (BMI > 25 kg/m2 or >23 kg/m2 in Asian Americans); and
  • One or more additional risk factors
    • Physical inactivity
    • First degree relative with diabetes
    • High-risk race/ethnicity (eg, African American, Latino, Native American, Asian American, Pacific Islander)
    • Women who delivered a baby weighing 9 lbs or more or were diagnosed with GDM and normal postpartum screening test results, repeat testing 1 to 3 years
    • Hypertension (>140/90 mmHG or on therapy for hypertension)
    • HDL cholesterol level <35 mg/dl and/or a triglyceride level of >250 mg/dl
    • Women with polycystic ovary syndrome
    • Hemoglobin A1C >5.7%, IGT or IFG on previous testing
    • Other clinical conditions associated with insulin resistance (eg, severe obesity, acanthosis nigricans)
    • History of CVD
