It cannot separate non- falciparum species. falciparum) and aldolase which is a pan-malarial antigen. The Binax assay contains both the HRP II (for P. Tests that detect pLDH do not generate persistent positive results following chemotherapy, like the HRP-II test.Ĭurrently, the only available RDT for malaria in the United States is the BinaxNOW® Malaria Test. falciparum from the non-falciparum species, but cannot distinguish between P. Test kits that are currently available detect pLDH from all four species of Plasmodium. Parasite lactate dehydrogenase (pLDH) is produced by asexual and sexual stages (gametocytes) of malaria parasites. Early tests reported false positives due to cross-reactions with rheumatoid factor, but these issues have reportedly been addressed and corrected. These tests have low sensitivities for detecting infections with low level parasitemias (90%). Therefore, HRP-II tests can remain positive for up to 2 weeks following chemotherapy and parasite clearance, as confirmed by microscopy. The HRP-II antigen is synthesized and released by trophozoite and immature gametocyte stages and persists in peripheral blood. falciparum HRP-II only and therefore diagnose only P. These tests generate results within 15 minutes and do not require skilled microscopists.Ĭommercially available kits for HRP-II detect P. Tests have been developed that detect antigens including the histidine-rich protein II (HRP-II), aldolase, and parasite lactate dehydrogenase (pLDH). ![]() ![]() Most tests use monoclonal antibodies and detect particular malarial antigens in blood specimens. Rapid diagnostic tests for malaria have been developed that employ immunochromatographic methods based on the detection of malarial antigens present in peripheral blood.
