You are being asked to be in a research study called the TrialNet Natural History Study of the Development of Type 1 Diabetes. As you know, TrialNet is an international research group dedicated to the study, prevention and early treatment of type 1 diabetes. The study will help us learn more about how type 1 diabetes occurs. In addition, the study will help us identify people who may be eligible for prevention trials. This study is being conducted at Florida Hospital Translational Research Institute for Metabolism and Diabetes (TRI-MD) and is part of a larger study that is being conducted at several sites. You recently participated in TrialNet Natural History Screening. If you were found to have autoantibodies in Screening you may be more likely to develop type 1 diabetes than other people.
