Figure 2From: Evaluation of the specificity of three enzyme-linked immunosorbent assays for detection of antibodies against Salmonella in bovine bulk milkThe specificity at different cut-off values of three different ELISAs detecting antibodies against Salmonella . The specificity and 95% confidence interval at different cut-off values of three different ELISAs detecting antibodies against Salmonella. A: Prionics Dublin ELISA (PrioCHECK® Salmonella Ab bovine Dublin ELISA), n=1065; B: a Danish in-house Dublin ELISA, n=1067; C: Prionics mixed ELISA (PrioCHECK® Salmonella Ab bovine ELISA), n=988. The red line represents the producer’s recommended cut-off value for these ELISAsBack to article page
