Insights on Autoimmune Diabetes
Type 1 diabetes is a chronic autoimmune disease characterized by insulin deficiency and resultant hyperglycemia. Over 90% of people with newly diagnosed type 1 diabetes have measurable antibodies against specific β-cell proteins, including insulin, glutamate decarboxylase, islet antigen 2, zinc transporter 8, and tetraspanin-7. Most people with a single autoantibody do not progress to type 1 diabetes, but seroconversion to the presence of two or more serum autoantibodies in children is associated with an 84% risk of clinical type 1 diabetes by the age of 18 years. Type 1 diabetes is a heritable polygenic disease with identical twin concordance of 30–70%, sibling risk of 6–7%, and a risk of 1–9% for children who have a parent with diabetes.

How do we diagnose Autoimmune Diabetes?
The diagnosis of autoimmune diabetes is based on a combination of clinical presentation, metabolic markers, and the detection of diabetes-specific autoantibodies. These are the key markers of autoimmune β-cell destruction and may appear years before clinical onset. The most relevant autoantibodies include: Anti-islet cell antibodies (ICA) – typically detected by Indirect Immunofluorescence Assays (IFA), Anti-insulin antibodies (IAA), Anti-GAD antibodies (GAD65), Anti-IA-2 antibodies, Anti-ZnT8 antibodies, typically detected by ELISA.
