The ROC curves show the comparison between the agar plate culture and other tests used. FECT formalin-ether concentration technique. The ELISA ROC had an AUC (area under the curve) of 0.955 with 100% sensitivity, the Baermann funnel technique had an AUC of 0.875 with 70% sensitivity, the formalin-ether concentration ROC had an AUC of 0.750 with 50% sensitivity, and the direct smear examination ROC had an AUC of 0.688 with 37.5% sensitivity
