Table 3 Diagnostic accuracy of XN-30 compared to malaria microscopy. Data with and without correction for qPCR confirmed sub-microscopic parasitemia cases

From: The XN-30 hematology analyzer for rapid sensitive detection of malaria: a diagnostic accuracy study

  XN-30, uncorrected (n = 837) XN-30, corrected* (n = 837)
  Positive Negative Positive Negative
Positive microscopy 234 3 253 3
Negative microscopy 21 579 2 579
Sensitivity 98.7%   98.8%  
Specificity 96.5%   99.7%  
PPV 91.8%   99.2%  
NPV 99.5%   99.5%  
ROC 0.98   0.99  
  1. *In case of incongruent results between malaria microscopy and XN-30, the microscopy data was adjusted to the PCR result
