Comparison of a Clinic-Based ELISA Test Kit with the Immunofluorescence Antibody Test for Assaying Leishmania infantum Antibodies in Dogs
Figure 1
ROC curve for the immunochromatographic assay for detection of anti-Leishmania IgG antibodies. -axis shows the false positive rate (specificity), and the -axis shows the true positive rate (sensitivity). A test with the perfect discrimination has a ROC curve that passes through the upper left corner. The area under the curve (AUC) is (). The ROC analysis shows that the cutoff point for the test with the best sensitivity/specificity is >0 (Se: 92.1%; Sp: 97.14% expressed as percentages).
