A smartphone-based end-to-end platform for multiplexed DNA diagnosis of malaria using paper-based microfluidic diagnostic tests, deep learning algorithms, and blockchain technology was validated through field tests in rural Uganda, achieving over 98% accuracy in identifying tested cases. The platform also offers secure geotagged diagnostic information for potential integration into infectious disease surveillance frameworks.
In infectious disease diagnosis, results need to be communicated rapidly to healthcare professionals once testing has been completed so that care pathways can be implemented. This represents a particular challenge when testing in remote, low-resource rural communities, in which such diseases often create the largest burden. Here, we report a smartphone-based end-to-end platform for multiplexed DNA diagnosis of malaria. The approach uses a low-cost paper-based microfluidic diagnostic test, which is combined with deep learning algorithms for local decision support and blockchain technology for secure data connectivity and management. We validated the approach via field tests in rural Uganda, where it correctly identified more than 98% of tested cases. Our platform also provides secure geotagged diagnostic information, which creates the possibility of integrating infectious disease data within surveillance frameworks. A smartphone-based system that uses deep learning algorithms for local decision support, and incorporates blockchain technology to provide secure data connectivity and management, can be used for multiplexed DNA diagnosis of malaria.
