Relative sensitivity and specificity of PostPInf (the probability of antibody positivity) for BRSV (left panel, n = 569) and BCV (right panel, n = 270)) in the last three month time period before subsequent bulk tank milk (BTM) testing versus cut-off value, when the subsequent BTM antibody-test was used as gold standard. Estimation of PostPInf was based on BTM antibody testing, herd location and animal movement data during the period January 2013–December 2016.
