Phase 1: Screening April, 2006
The screening phase of the Natural History Study identifies people at increased risk for developing type 1 diabetes.
People who qualify and choose to participate in the Natural History Study may also be offered an opportunity to enter a diabetes prevention study in the future.
To be screened, you must fulfill at least one of the two conditions below:
1 to 45 years of age and have a brother, sister, child, or parent with type 1 diabetes
1 to 20 years of age and have a cousin, aunt, uncle, niece, nephew, half sibling, or grandparent with type 1 diabetes
What is the purpose of these screening tests?
The first screening test looks for autoantibodies associated with type 1 diabetes in your blood. Autoantibodies are proteins made by the immune system.
Autoantibodies are a sign that your immune system may be attacking the insulin- producing cells in your pancreas. Having these autoantibodies places you at greater risk for developing diabetes.
About 3 to 4 percent of family members of people with type 1 diabetes will have autoantibodies in their blood.
To do this screening test, a small sample of blood is drawn from your arm at a TrialNet clinic or you can ask us to send you a test kit that you can take to a local lab or your own doctor to have your blood drawn. Then the blood sample is sent to the TrialNet central laboratory for analysis.
In 4 to 6 weeks, you will learn your test results.
