RADx® Tech and ATP Programs



word cloud with stats on RADx Tech program

The RADx® Tech programs is a component 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 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.

Innovation Funnel - Beyond COVID-19 Projects

NIBIB is partnering with others to leverage the Innovation Funnel to address a range of health care problems. Learn about these programs, the challenges being addressed, and research opportunities.

RADX Tech Overview and Outcomes

Read an overview of the RADx Tech program and the impact on addressing the COVID-19 pandemic. 


The MakeMyTestCount.org website is an easy way to anonymously report test results for any brand of at-home COVID-19 test. This helps public health departments to assess needs and provide resources. Report your test results here

Learn about a fast, cost-effective method to detect the circulation of SARS-CoV-2 variants using a genotyping approach. 

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.

Available Now: Best Practice Recommendations document for designing and developing COVID-19 tests that are more accessible. This is part of the RADx Tech effort to work with collaborators to develop at-home diagnostic tests for COVID-19 that can be used independently by people with disabilities. The initial focus is with people who are blind or have low vision, people with fine motor difficulties, and home tests for older adults. 

Learn about this effort to securely send results from a self-administered test to public health systems. The process is designed to work with different tests and includes an option for anonymous reporting. 

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.

Home Test to Treat was an entirely virtual community health intervention that provided free COVID-19 and flu health services including at-home rapid tests, telehealth sessions, and treatments. The program has concluded and research outcomes from this intervention will be made available in fall 2024.

The Say Yes COVID Test project is a cooperative effort from state and local health departments, NIH, and CDC.  This program offered access to free, rapid, at-home COVID-19 testing in select communities throughout the U.S. The program has ended. Information and outcomes about the program can be found on this webpage.
