The Role of Ultrasensitive Molecular Methods for Detecting Malaria-The Broader Perspective

Abstract

Ultrasensitive molecular diagnostics are lowering the limit of detection for malaria parasites in the blood and providing insights not captured by conventional tools such as microscopy and rapid antigen tests. Low-level malaria infections identified by molecular tools may influence clinical outcomes, transmission events, and elimination efforts. While many ultrasensitive molecular methods require well-equipped laboratories, technologies such as loop-mediated isothermal amplification and recombinase polymerase amplification provide more portable and analytically sensitive solutions. These tools may benefit asymptomatic patient screening, antenatal care, and elimination campaigns. We review the recent evidence, offer our perspective on the impact of these new tests, and identify future research priorities.
