Blood test to find early signs of type 1 diabetes in at-risk families

This study is looking for early warning signs of type 1 diabetes in people who are related to or close friends with someone who has the disease. Researchers will take a small blood sample from you to check for special markers called autoantibodies — these are signs that your immune system may be attacking the cells that make insulin, even before you feel sick. If you have these markers, the research team will follow up with you to monitor your health.

Type 1 diabetes can develop quietly over months or years before symptoms show up. By finding people with early warning signs now, doctors may be able to help prevent or delay the disease, and researchers can learn more about how it develops.
