Diagnosing T1D
Labcorp can help deliver accurate diagnoses for your patients
To serve as your source for identifying and managing patients at risk for development of type 1 diabetes, we offer the Diabetes Autoimmune Profile. This combined test evaluates well-characterized islet antibodies—glutamic acid decarboxylase autoantibody (GAD-65), insulin autoantibodies (IA), Insulinoma-associated-2 autoantibodies (IA-2), and zinc transporter-8 autoantibodies (ZnT8)8 . Measuring for all four autoantibodies is recommended to achieve maximum sensitivity for detecting autoimmune diabetes. Studies have shown that the combined measurement raised detection rates to 98% in new-onset T1D.9
A positive result for more than one antibody is associated with a higher likelihood of T1D and can help with staging presymptomatic T1D.
