Diabetes ScreeningWho Should Get Screened
People who have a family member with type 1 diabetes should be screened for type 1. Also, people who have a family history of any of a variety of autoimmune diseases may consider being screened for type 1 diabetes.

According to the American Diabetes Association, screening for pre-diabetes or type 2 is recommended for:

  1. People who are living with overweight or obesity (BMI ≥25 kg/m2 or ≥23 kg/m2 in Asian American individuals) and have one or more of the following risk factors:
    • First-degree relative with diabetes
    • High-risk race/ethnicity (e.g., African American, Latino, Native American, Asian American, Pacific Islander)
    • History of cardiovascular disease
    • Hypertension (≥130/80 mmHg or on therapy for hypertension)
    • HDL cholesterol level <35 mg/dL (0.90 mmol/L) and/or a triglyceride level >250 mg/dL (2.82 mmol/L)
    • Individuals with polycystic ovary syndrome
    • Physical inactivity
    • Other clinical conditions associated with insulin resistance (e.g., severe obesity, acanthosis nigricans)
  2. People with prediabetes (A1C ≥5.7% [39 mmol/mol], Impaired Glucose Tolerance, or Impaired Fasting Glucose) should be tested yearly.
  3. People who were diagnosed with Gestational Diabetes should have lifelong testing at least every 3 years.
  4. For all other people, testing should begin at the age of 35 years.
  5. If results are normal, testing should be repeated at a minimum of 3-year intervals, with consideration of more frequent testing depending on initial results and risk status.
  6. People with HIV.

What it is, what it isn’t:

  • What it is: A type 1 diabetes screening test is a blood sample that looks for certain antibodies associated with type 1 diabetes. If the blood sample indicates that a person is producing certain antibodies, the next step is another blood sample to check if glucose is normal or elevated. Having an antibody may indicate that there is a risk of developing type 1 diabetes, but it is not a guarantee that a person will develop it. Discuss the test results with your medical team. If the test is negative, the blood sample can be repeated every year.
  • What it isn't: Taking a test to check for antibodies in the body is not a test to look at a person's genes. It does not tell you if there is any genetic risk of developing type 1 diabetes. If a blood sample is negative for antibodies today, it does not promise that in the future, they will never appear.
  • What it is: A type 2 diabetes screening test is a blood sample that checks whether glucose is in range or elevated.
  • What it isn't: Getting a type 2 diabetes screening test that finds your blood glucose is in range today doesn't promise that your blood glucose will never rise in the future.
