A group of U.S. Senators visited the Bethesda campus of the National Institutes of Health on May 17, 2021, to learn more about NIH’s response to COVID-19. Part of the NIH tour was a demonstration of diagnostic technologies developed by the NIBIB-led RADx Tech and ATP programs. These programs are part of the NIH RADx Initiative. The Senators viewed at-home, point-of-care, and laboratory tests and testing products. With support from the RADx programs, many of these technologies are now on the market.
