The Diabetes Risk Test is a quick and easy tool for assessing risk for type 2 diabetes.

Laboratory tests to ascertain the blood glucose level of at-risk patients should be repeated every 1–3 years. Women with a history of gestational diabetes should be screened 6–12 weeks postpartum and every year thereafter if prediabetes is diagnosed, or every 3 years thereafter if the postpartum test is normal.1
