The National Institutes of Health has issued two new funding opportunities for diagnostic test manufacturers to develop the next generation of COVID-19 tests, with a major focus on accessibility. The funding opportunities are part of the Rapid Acceleration of Diagnostics (RADx) Tech program, managed by the National Institute of Biomedical Imaging and Bioengineering (NIBIB). The new programs may award up to $300 million in funds from the American Rescue Plan Act of 2021 to support the accelerated development of tests and provide regulatory guidance during the COVID-19 pandemic and beyond.
