False-positive results of a Plasmodium falciparum histidine-rich protein 2-detecting malaria rapid diagnostic test due to high sensitivity in a community with fluctuating low parasite density.


The persistence of parasite histidine-rich protein 2 (HRP2) in the circulation after parasite clearance has been considered a drawback for rapid diagnostic tests (RDTs) targeting HRP2 and a major cause of false-positive results. This paper reports results of a study into whether a proportion of RDT HRP2 false-positive cases carried parasites using… (More)
