ELISA test parameters when using protein G or anti-deer conjugates with elk serum
S/P cut-off AUC [95% CI] Se [95% CI] Sp [95% CI] PPV [95% CI] NPV [95% CI]
Protein G 0.22 0.81 [0.65; 0.91] 73% [50; 89] 90% [68; 99] 89% [65; 99] 75% [53; 90]
Anti-deer 0.29 0.85 [0.71; 0.95] 68% [45; 86] 100% [83; 100] 100% [78; 100] 74% [54; 89]

Sample-to-positive (S/P) ratio cut-off values as determined by Receiver Operational Curve (ROC) analysis, the area under the curve (AUC), and the resulting sensitivity (Se), specificity (Sp), positive predictive value (PPV) and negative predictive value (NPV).
