Specificity, sensitivity, and positive and negative predictive values for uRDT, standard RDT, and microscopy compared to reference methodsa

  • a The references (Ref) are combined reference uPCR plus Quansys (PfDNA or Plasmodium DNA plus PfHRP2), reference P. falciparum DNA detection by uPCR, and reference PfHRP2 detection by Quansys.

  • bThe specificity (Sp) and sensitivity (Se) and 95% confidence interval are shown.

  • cThe positive predictive value (PPV) and negative predictive value (NPV) and 95% confidence interval are shown.

  • dSee Table 3 for details on uRDT false-positive samples.
