C0VID-19 Testing Technologies

We address the current situation of population-wide and speedy testing for SARS-CoV-2 and review different technologies available, such as molecular and rapid antigen tests, serology and antibody tests, and tests for managing COVID-19 patients. We consider products authorized by the FDA to diagnose and detect COVID-19 infections. This review covers pooled testing, screening programs, and surveillance testing to enable quicker screening. We also discuss the potential challenges in terms of detecting low infectivity levels, variants mapping, cost reduction, training a large healthcare workforce, and providing test kits to the general public. We aim to comprehend the possibility of widespread access to COVID-19 testing and diagnostics in the near future, while being aware of the possible challenges during the development and distribution of new testing platforms.
