Of the 190 samples that were negative by light microscope, the  Pf® showed 11 false positive and 179 true negative results, and from a total of 210 samples positive by light microscope,  Pf® accurately diagnosed 200 true malaria cases. Taking the light microscopy as a standard test for malaria, the sensitivity, specificity, positive predictive value and negative predictive value of k Pf® is 95.2% [cofidence interval (CI)=92.4–97.1], 94.2% (CI=91.1–96.3), 94.8% (CI=92.0–96.7) and 94.7% (CI=91.6–96.8), respectively.
