Criteria for testing for diabetes or prediabetes in asymptomatic adults

1. Testing should be considered in all adults who are overweight (BMI ≥25 kg/m2 or ≥23 kg/m2 in Asian Americans) and have additional risk factors:
 • physical inactivity
 • first-degree relative with diabetes
 • high-risk race/ethnicity (e.g., African American, Latino, Native American, Asian American, Pacific Islander)
 • women who delivered a baby weighing >9 lb or were diagnosed with GDM
 • hypertension (≥140/90 mmHg or on therapy for hypertension)
 • HDL cholesterol level <35 mg/dL (0.90 mmol/L) and/or a triglyceride level >250 mg/dL (2.82 mmol/L)
 • women with polycystic ovary syndrome
 • A1C ≥5.7%, IGT, or IFG on previous testing
 • other clinical conditions associated with insulin resistance (e.g., severe obesity, acanthosis nigricans)
 • history of CVD
2. For all patients, particularly those who are overweight or obese, testing should begin at age 45 years.
3. If results are normal, testing should be repeated at a minimum of 3-year intervals, with consideration of more frequent testing depending on initial results (e.g., those with prediabetes should be tested yearly) and risk status.
