 We have developed an optimized diagnostic strategy ODS based on integrating Clinical information a validated clinical probability model, Biomarkers GAD, Islet antigen-2 IA2 and ZnT8 autoantibodies and Genetic testing for MODY. This has the potential to determine the subtype of diabetes in young adults leading to improved treatment and care. Prior to undertaking a comprehensive RCT to test our ODS against standard care, we must first undertake this pilot study to assess the feasibility of such a project.
