Fig. 1From: Investigation of Plasmodium falciparum pfhrp2 and pfhrp3 gene deletions and performance of a rapid diagnostic test for identifying asymptomatic malaria infection in northern Ethiopia, 2015Selection of samples for pfhrp2 and pfhrp3 genotyping by ratio of LDH to HRP2. Vertical hashed red line designates the threshold for antigen positivity signal for pLDH antigen and the horizontal hashed red line designates the threshold for antigen positivity signal for HRP2. The region shaded in orange denotes values where DBS samples were positive for pLDH antigen, but negative for HRP2 antigenBack to article page
