Study Purpose:  To screen relatives of people with type 1 diabetes. They have about 15 times greater risk for developing the disease than people with no family history.  


To be enrolled in this study, you must meet certain requirements. You may be eligible to participate if you meet the associated criteria:

  • 1-45 years old and have a brother, sister, child, or parent with type 1 diabetes


  • 1-20 years old and have a cousin, aunt, uncle, niece, nephew, half-brother, half-sister, or grandparent with type 1 diabetes.


(Your relative has type 1 diabetes if he or she was diagnosed before age 40 and needed insulin injections within a year.)

Study Commitment:

  • A screening visit for blood draw to test for three diabetes autoantibodies
  • Follow-up visits depend on screening visit results
    •  If you are negative for those three diabetes autoantibodies you are at low risk for developing diabetes.
    •  If you are a positive for a single autoantibody
      •  You will come in for a baseline monitoring visit to determine eligibility for annual or semi-annual (every 6 moths) monitoring visits.
    •  If you are positive for two or more autoantibodies
      •  You will come in for semi-annual (every 6 months) monitoring visits.

Study Procedures:


  • Blood draws for autoantibodies and Hemoglobin A1c
  • Oral Glucose Tolerance Test (OGTT)
