Testing to assess risk for future diabetes in asymptomatic people should be considered in adults of any age who are overweight or obese (BMI ≥ 25 kg/m2 or ≥ 23 kg/m2 in Asian Americans) and who have one or more additional risk factors for diabetes.• For all patients, testing should begin at age 45 years.
If tests are normal, repeat test at a minimum of 3- year intervals.
To test for prediabetes, fasting plasma glucose, 2-h
plasma glucose after 75-g oral glucose tolerance test,
and A1C are equally appropriate.
In patients with prediabetes, identify and treat other
cardiovascular disease risk factors. •
Testing should be considered in children and
adolescents who are overweight or obese and who
have two or more additional risk factors for diabetes
