Overall result of parasitological examinations
	Positive	Negative
XN-31 result
Positive	13	0

Predictive value and efficiency
PPV	NPV	Efficiency
100%	100%	96%

PPV: positive predictive value, defines the probability of having Plasmodium in a sample with a positive result. NPV: negative predictive value, describes the probability of not having Plasmodium in a sample with a negative test result. Efficiency is the proportion of correctly classified samples as negative or positive among all samples
