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.
