nPOD central AAb core laboratoryThe nPOD central AAb core laboratory has a long history of excellence in the type 1 diabetes AAb field 10, 13, 15, 21, 22, participating routinely in the Diabetes AAb Standardization Program (DASP), now renamed IASP. The nPOD central AAb core began testing for ZnT8A in nPOD cases using RBA prior to the introduction of the ZnT8A ELISA. This core also tests for IAA as there is currently no reliable ELISA for this analyte. Every case with available serum that is referred to nPOD is tested via RBA for GADA, IA‐2A, ZnT8A and IAA for either confirmation of the ELISA screening results, or for determination of final AAb status. In cases of discrepancy, the RBA supersedes the ELISA as the result reported on the nPOD website (www.jdrfnpod.org).
