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.
