| Additional information | Islet cell antibody titer reported in JDF units (Reference Range: less then 1.25 JDF). End point titers are compared to a single international reference standard and values are reported in JDF (Juvenile Diabetes Foundation) units. Type 1 diabetes is characterized by lymphocytic cell infiltrate of the pancreatic islets. 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. |
