a Distribution of the SNRs of the IDEXX-positive (n = 142) and IDEXX-negative (n = 42) serum samples of the clinical sera obtained from the IBV protein microarray. The threshold was defined as 2. The diagnostic sensitivity and specificity of the assay were greater than 90%. b ROC curve obtained with GraphPad Prism 6 software with positive (n = 142) and negative (n = 42) samples. The AUC was 0.9993, indicating that the IBV protein microarray is a reliable test
