Methodology: Radiobinding Assay
Clinical Significance: Type 1 diabetes is characterized by a lymphocytic cell infiltrate of the pancreatic islets. Insulin Antibody is useful in assessing lower titers of autoantibody in patients with diabetes, detecting insulin autoantibody in patients who are ''prediabetic,'' and in detecting autoantibody in patients with other autoimmune disorders.

Measurement of GAD-65, ICA-512, and Insulin Antibody is a highly sensitive means to assess risk and predict onset of Type I diabetes. There is a correlation between the number of positive antibodies and the antibody titers versus the severity of the autoimmune process.
