This study is providing annual blood tests looking at diabetes autoantibodies for first degree relatives of patients diagnosed with type 1 diabetes who are between the ages of 1 and 45. It will also provide "diabetes screening" for second and third degree relatives age 1-20. Often parents and/or relatives wonder "if they will get diabetes" down the road or if additional offspring are "at risk" for type 1 diabetes. This study aims at assisting families with free blood testing. If positive, participants will be eligible for "prevention studies". MUSC is currently only participating in the "screening" portion of TrialNet.
