Application of multiple binding sites for LAMP primers across P. falciparum genome improves detection of the parasite from whole blood samples

Abstract

Malaria remains a significant health concern, particularly in regions with widespread prevalence. As the transmission rates decrease, there is a rise in low-density infections with the causative parasite, P. falciparum, that often escape detection through standard point-of-care diagnostic tools. In-low transmission areas, even few undetected cases can trigger outbreaks, necessitating rapid and sensitive diagnostics. Loop-mediated isothermal Amplification (LAMP) stands out as a nucleic acid technique that can easily utilizes un-processed samples such of saliva, urine, and lysed whole blood templates for a sensitive detection. However, most nucleic acid tests detect genes with few copies per parasite making it difficult to detect low-density parasitaemia.
