Comparison of the test characteristics of the novel competitive ELISA and the previously described indirect immunoassays with the available set of porcine plasmas.

Respective ELISA results for a set of 90 tsetse exposed (10 repeated samplings of the 9 exposed pigs starting three weeks after the initial exposure) and 21 non-exposed porcine plasmas (9 pre-immune and 12 repeated samplings of the control pig) were interpreted based on the calculated cut-off values (see methods section). TP true positive, TN true negative, FP false positive, FN false negative, PPV positive predictive value, NPV negative predictive value.Comparison of the test characteristics of the novel competitive ELISA and the previously described indirect immunoassays with the available set of porcine plasmas.
