Statistical comparison of ova and parasite results and reference laboratory ELISA to DFA with calculated sensitivity and specificity

Reference laboratory test	Sensitivity (95% CI)	Specificity (95% CI)	Prevalence adjusted % agreementa
Ova and Parasite (O&P) Test	81.2 (72.4–87.7)	93.4 (85.2–97.5)	92.7
ProSpecT Microtiter Plate ELISA	94.1 (87.4–97.5)	97.4 (90.4–99.8)	97.2

^aPercent agreement was adjusted for reported prevalence of infection determined by DFA as described in materials and methods
