Overall diagnostic accuracy of the ELISA using plasma or egg-yolk samples in comparison to FECs. Area under the ROC curves (AUC) for the ELISA assays based on plasma antibody, egg yolk antibody or for faecal egg counts in chickens experimentally infected with A. galli or H. gallinarum. The dashed diagonal line corresponds to the half of the maximum AUC (1.0). The farther the location of the ROC curve is from the diagonal line, the higher the total test accuracy
