  1. 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
