RADx® Tech and ATP Programs

word cloud with stats on RADx Tech program

The RADx® Tech/ATP programs are components of the overarching RADx Initiative at NIH to speed innovation in the development, commercialization, and implementation of technologies for COVID-19 testing. The RADx Tech/ATP innovation funnel was designed to compress the customary technology development timeline from years down to just months.  This was accomplished by employing, in parallel, expert teams to address technical, regulatory, clinical, and commercialization requirements. Launched on April 29, 2020, the RADx programs were able to validate, de-risk, scale up, manufacture, and deploy novel tests through a seamless pipeline by fall 2020. 

These programs have increased testing capacity in the U.S. by billions. As the COVID-19 pandemic evolves, NIBIB continues to support projects to fill unmet needs in diagnostic testing.

The RADx Tech and ATP programs leverage the Point of Care Technology Research Network and joined with numerous other federal agencies, offices, NIH institutes, and contractors.

Learn more about this accelerated pathway designed to help bring to market over the counter diagnostic tests for COVID-19 that are not yet authorized by the FDA.

When to Test tool now has an individual calculator to help guide individuals and families on COVID-19 testing. The Testing Impact Calculator also includes tools to help organizations plan for and develop testing strategies, and playbooks for pooled testing and K-12 schools. This site includes other resources on testing strategies and obtaining supplies. Try the calculator.

The Say Yes COVID Test project is a cooperative effort from state and local health departments, NIH, and CDC.  This program offers access to free, rapid, at-home COVID-19 testing in select communities throughout the U.S. Learn more.
