Figure 2. ROC curves and AUC of CCA results using Kato-Katz as reference tests.

The receiver operating characteristic (ROC) curves and the area under the curve (AUC) of CCA and CCA-L are presented using either single (A), triplicate (B) and nine Kato-Katz (C) thick smears as the reference tests. The discriminating powers of single CCA and CCA-L were high in all cases.
