Receiver operating characteristic (ROC) curve analyses comparing trichloroacetic acid (TCA), frozen, heating and alkaline methods in detecting O. viverinni infection in Sample Set 1 (n = 50).
ROC curve, using individuals from Sample Set 1 were used to compare the diagnostic performance of antigen detection TCA, frozen, heating and alkaline treatment methods in the O. viverrini Excretory Secretory assay. Sensitivity against 1-specificity for the antigen levels detected by each ELISA method from confirmed positives and negatives by the gold standard method formalin ethyl-acetate concentration technique (FECT).
