What are the screening recommendations and criteria for the diagnosis of diabetes?
Universal screening is recommended at age 45 years. Younger individuals should be screened if they have risk factors for type 2 diabetes (i.e., obesity, family history of diabetes, hypertension, and hyperlipidemia). Prediabetes identifies individuals at high risk for developing diabetes.
