Accessing Care, Clinical Trials and Screening for Underserved Children and Adults With Type 1 Diabetes (ACCESS-T1D)

The purpose of this study is to identify people with T1D or celiac disease (CD) early in the course of their disease and to improve the methods of screening for these diseases.

The study will screen people who may be at risk for T1D because they have at least one person in the family with probable T1D. It can be a parent or a sibling. It can also be a second-degree relative, like nieces, nephews, aunts, uncles, grandchildren, or cousins. A relative of someone with T1D is at a higher risk of getting the disease as they are people with other autoimmune diseases. It is possible to detect T1D or CD before it shows any symptoms of high blood sugar. Sometimes, particularly in people who develop T1D in adult life, the disease is misdiagnosed as type 2 diabetes. The treatment and care for the two diseases are different.

Inclusion Criteria 1. Able to provide informed consent (adults 18 and above) and assent if seven or above. Legally authorized representative (LAR) is able to provide consent in case of minors or in case of adults unable to consent. 2.

Those diagnosed with other forms of diabetes which are suspected of being T1D because of a BMI ≤28 or progression to insulin dependence within 3 years from diagnosis. 3. Resides in the following Counties: Orange, Seminole, Osceola, Lake, Volusia, Brevard, Polk, Hillsborough. Exclusion Criteria 1. People with a diagnosis of type stage 3T1D or T1D clinical definition per ADA Standards of Care 2. History of organ transplant 3. Be deemed unable or unlikely to comply with the protocol. 4. Presence of any condition that, in the opinion of the Investigator, compromises participant safety or data integrity or the participant's ability to complete study visit/s.
