Key concepts

  • HHS coordinates COVID-19 testing.External The Department of Health and Human Services (HHS) works across the U.S. government, including with the Department of Defense, to review potential products from public and private sectors to identify promising candidates that could detect, protect against or treat COVID-19 for development and licensure. HHS is providing rapid point-of-care tests and devices to public health labs (PHLs) in every state and territory, and Washington, D.C.
  • FDA issues emergency use authorizations for COVID-19 tests.External The FDA has issued several Emergency Use Authorizations (EUAs) for the use of new viral tests to detect the SARS-CoV-2 virus, which causes COVID-19. During public health emergencies declared under section 564 of the FD&C Act, the FDA is able to issue EUAs when certain criteria are met that allows for the use and distribution of potentially life-saving medical products to diagnose, treat, or prevent the disease, which can include viral tests.
  • CDC provides guidance and resources for laboratories. CDC provides interim guidance and resources for laboratory professionals working with specimens from persons under investigation (PUI) for COVID-19. In order to protect health care workers and laboratorians, CDC provides laboratory biosafety guidelines for handling and processing specimens associated with COVID-19.
