Table 2 Contingency tables with Cohen’s kappa (κ) values (95% CI) for paired serum and meat juice samples analysed on the ArrayTube platform. Samples originate from 87 pigs slaughtered in 3 German abattoirs between October 2016 and January 2017

From: Use of meat juice and blood serum with a miniaturised protein microarray assay to develop a multi-parameter IgG screening test with high sample throughput potential for slaughtering pigs
