Scatter plot of the OD405 values obtained from 168 paired turkey serum samples from Ontario turkey farms using TCoV N- and a whole-virus IBV-based commercial ELISA. Only a modest correlation (R = 0.2623) was observed between the recombinant antigen TCoV N-based ELISA and the commercial IBV whole-virus-based ELISA. The usual OD405 cutoff value for the N-based ELISA is 0.180 (horizontal dotted line), and the usual OD650 cutoff value for the whole-virus IBV-based ELISA is 0.100 (vertical dotted line).
