asymptomatic adult individuals Testing for diabetes should be considered in all individuals at age 45 years and above,
particularly in those with a BMI 25 kg/m2*, and, if normal, should be repeated at 3-year intervals.

American, Asian American, Pacific Islander)• have delivered a baby weighing >9 lb or have been diagnosed with GDM• are hypertensive (140/90 mmHg)• have an HDL cholesterol level <35 mg/dl (0.90 mmol/l) and/or a triglyceride level >250 mg/dl
(2.82 mmol/l)• have polycystic ovary syndrome (PCOS)• on previous testing, had IGT or IFG• have other clinical conditions associated with insulin resistance (e.g., PCOS or acanthosis
nigricans)• have a history of vascular disease• * May not be correct for all ethnic groups. PCOS, polycystic ovary syndrome
