Report of a collaborative trial to investigate the performance of the R5 enzyme linked immunoassay to determine gliadin in gluten-free food

Abstract

Both assays are comparable and robust. The repeatability and reproducibility data are in a range that is acceptable for ELISAs. Kits from both suppliers fulfilled performance criteria of regular ELISA methods, and it is shown that both ELISA kits guarantee a sensitivity of 1.5 ppm gliadin for gluten-free food.
