On Sept. 2, 2020, the National Institutes of Health (NIH) announced $129.3 million in scale-up and manufacturing support for a new set of COVID-19 testing technologies as part of its Rapid Acceleration of Diagnostics (RADx) initiative. NIH is awarding contracts to nine companies for technologies that include portable point-of-care tests for immediate results and high-throughput laboratories that can return results within 24 hours. These tests add to initial awards made to seven companies on Jul. 31, 2020.

In addition to NIH support, aspects of some of the testing technologies have been supported by the Biomedical Advanced Research and Development Authority (BARDA), also in the Department of Health and Human Services, and by the Defense Advanced Research Projects Agency (DARPA), in the Department of Defense.

These contracts support several novel technologies, some that use RT-PCR, a highly sensitive way to qualitatively detect nucleic acid from SARS-CoV-2. Included is a portable, battery-powered RT-PCR device that gives accurate results in 15 minutes, and a portable mini-lab with reagent flexibility that can perform RT-PCR assays in community hospitals and clinics in underserved, rural populations. Additional technologies include a lateral-flow immunoassay test strip that can be read without specialized equipment (similar to home pregnancy tests) and a sample concentrating method that significantly improves the sensitivity and performance of many different types of tests. Five high-throughput laboratories will provide an expanded network of coverage for fast-turnaround laboratory tests in regions of national need. Each of these labs will manage the collection, analysis, and reporting of tens of thousands of tests per day at each site, significantly expanding national testing in September.
