Diabetes risk check
Type 2 diabetes risk test
Seven questions about you, your family and your health. You get a score from 0 to 10, what it means, and whether a blood test makes sense.
Your answers
The questions are in our own words; the points follow the published score. Nothing you enter leaves this page.
What you will see
Your score out of 10, which zone it falls in, the points behind it, and what the original study suggests doing next.
Educational only, not medical advice. A screening score, not a diagnosis.
Source
Bang H et al., Annals of Internal Medicine 2009, as used in the American Diabetes Association's Type 2 Diabetes Risk Test (which adds a point for gestational diabetes). Questions in our own words.
Validated in
US adults aged 20 and older: built in NHANES 1999 to 2004, checked in NHANES 2005 to 2006 and in the ARIC and CHS community studies.
Limits
Flags undiagnosed diabetes; it does not diagnose diabetes or prediabetes. The study had no data on pregnancy or gestational diabetes. Uses BMI, which can be misleading for some bodies; the ADA suggests a lower BMI line (23) for Asian American adults.
Why check
About 40.1 million people in the US have diabetes, and about 11.0 million adults with diabetes do not know they have it (CDC). Another 115.2 million US adults have prediabetes (CDC). Type 2 diabetes often has no clear symptoms for years, which is why short risk scores like this exist.
Where the score comes from
The researchers looked for the few things that best predicted undiagnosed type 2 diabetes in US adults: age, sex, family history, high blood pressure, physical activity and weight for height (Bang 2009). Those six factors make up the published score. The American Diabetes Association's version adds one point for women who have had gestational diabetes (ADA), and we follow that version. At a cut point of 5 or more, the score picked up 79% of people with undiagnosed diabetes in the national survey data and 72% in the community studies (Bang 2009). The American Diabetes Association uses this scoring in its own risk test (ADA).
What to do with your result
Whatever your score, the US Preventive Services Task Force recommends screening adults aged 35 to 70 who have overweight or obesity (USPSTF 2021), and the ADA recommends testing all adults from age 35 (ADA Standards 2026). A score of 5 or more is a good reason to ask for an A1C or fasting glucose test sooner. CDC lists further risk factors this score does not ask about, such as fatty liver disease and some racial and ethnic backgrounds (CDC).
