Probability of detecting influenza A virus (IAV) in swine oral fluids by RT-qPCR. Superscripts reflect significant differences (p < 0.05) in assay performance between 13 assays performed in 8 laboratories (A to H). Row groups indicate similar probability detection dose 50 (DD50), that is, the inoculum dilution at which there was a 50% probability of detection (10–4.68 to 10–6.68). Reprinted from Goodell et al.
