Fig. 5From: Establishment of enzyme-linked immunosorbent assays based on recombinant S1 and its truncated proteins for detection of PEDV IgA antibodyROC analysis of truncated S1 ELISA. A total of 213 pig serum samples were tested for the presence of anti-PEDV IgA by S1/S1T1/S1T2/S1T3-ELISA and by IFA. The sensitivity/specificity and the area under curve (AUC) of S1/S1T1/S1T2/S1T3-ELISA was determined by ROC analysis taking IFA results as standardBack to article page
