The Autoantibody Core at the University of Florida serves as the coordinating center for nPOD screening lab partners (LABS,Inc and Viracor-IBT Laboratories). Combi-kit manufacturing and quality control/assurance measures are managed here. Additionally, the UF Autoantibody Core tests all nPOD samples for autoantibodies to GAD, IA-2, and ZnT8 by ELISA.
