Abstract

The Brazilian Health System consists of a set of actions and services that assist the population through strategies aimed at the promotion, protection, and health recovery. One of the highlights is prevention, which includes the diagnosis and early treatment of diseases. The detection and classical identification of pathogens are based on microscopy and culture, however the low sensitivity; the need for trained professionals and adequate infrastructure leads, in some cases, to the failure of the diagnosis and in the delay to start treatment. Objective: to develop CEL, an equipment for LAMP (Loop-Mediated Isothermal Amplification) assays for use in low-resource settings laboratories. Results: Protocols were standardized for five important diseases found in the Amazon region: tuberculosis, malaria, dengue, mayaro and oropouche fevers. The equipment has integrated photometric detection, with the capacity of eight simultaneous reactions, detecting the color change observed in the positive reactions. The results are shown in an easy-to-read alphanumeric display, even for people with no experience with the technique. The results can also be transferred by bluetooth to a smartphone with the CEL App, where it is possible to see the results in a graphical interface. Conclusion: Once CEL is a low-cost device, developed for molecular diagnostics, it can represent an alternative to the expansion of the molecular diagnosis in the services of the primary health attention, allowing higher population access, even in remote areas.
