This is particularly true in surveillance of malaria at the population level that includes so-called “asymptomatic” individuals. Methods The development of the first ultrasensitive loop mediated amplification method capable of detecting malaria from both whole blood and dried blood spots (DBS) is described. The 18S rRNA and corresponding genes that remain stable on DBS for up to 5 months are targeted. Results In the case of Plasmodium falciparum, lower limits of detection of 25 parasite/mL and 50–100 parasite/mL from whole blood and DBS were obtained, respectively. A sensitivity of 97.0% (95% CI 82.5–99.8) and specificity of 99.1% (95% CI 97.6–99.7) was obtained for the detection of all species in asymptomatic individuals from Africa and Asia (n = 494). Conclusion This tool is ideally suited for low middle-income countries where malaria is endemic and ultrasensitive surveillance of malaria is highly desirable for elimination.Ultrasensitive loop mediated isothermal amplification (US-LAMP) to detect malaria for eliminationJournal Article2019-10-20enThe Author(s)https://doi.org/10.1186/s12936-019-2979-4
