Rapid Diagnostic Tests (RDTs) play a pivotal role in diagnosing infectious diseases, particularly in Point of Care (POC) settings with limited resources1. Despite their advantages, RDTs often face challenges in producing accurate quantitative results and are susceptible to interpretation errors due to factors like poor lighting and physical barriers. This paper introduces the Rapid Diagnostic Reader (RDR) as a solution to enhance the accuracy and reproducibility of RDTs, eliminating subjective interpretation. Furthermore, we propose the adoption of Quantifiable Units (QUs), a universal scale for interpreting RDT results. QUs offer a standardized method for precisely quantifying RDT results with the aid of the RDR that can be easily grasped by individuals at varying levels of training. This approach not only simplifies the interpretation of diagnostic results for healthcare professionals and the general public but also integrates seamlessly with electronic health records and laboratory systems, automating and quality assuring the result transfer process.
