Fig. 2From: Detecting asymptomatic carriage of Plasmodium falciparum in southern Ghana: utility of molecular and serological diagnostic toolsComparisons of PET-PCR, nPCR and the HRP2 bead assay detection tools to Microscopy (Gold standard). A Venn diagram illustrating the number of positive parasites by the four methods, A High transmission site, the four methods identified 8 samples as positive for the parasites, 6 positive samples between Nested PCR and HRP2 bead assay, and 0 between Microscopy and HRP2 bead assay, and 4 positive samples between PET-PCR and N-PCR. B Low transmission, the four methods did not identified any samples as positive for the parasites, 3 positive samples between Nested PCR and HRP2 bead assay, and no positive parasite between Microscopy and HRP2 bead assay, and also no positive sample between PET-PCR and Nested PCRBack to article page
