Microscopy and field adaptable rapid diagnostic tests (RDTs) are not sensitive and specific in certain conditions such as poor training of microscopists, lack of electricity, or the inability to detect non-falciparum malaria. More sensitive point of care testing (POCT) would reduce delays in diagnosis and initiation of therapy. In the current study, we have evaluated the efficacy of non-instrumented nucleic acid amplification (NINA) coupled with LAMP for detection of traveler’s malaria (n = 140) in comparison with microscopy, nested PCR, and the only FDA-approved rapid diagnostic test. NINA-LAMP was 100% sensitive and 98.6% specific when compared to nested PCR. For non-falciparum detection, NINA-LAMP sensitivity was 100% sensitive compared to nested PCR whereas RDT sensitivity was 71%. LAMP is highly sensitive and specific for symptomatic malaria diagnosis regardless of species in a POCT setting.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
