The United States has authorised its first rapid at-home test for Covid-19, which is available over-the-counter and produces a result in around 20 minutes.
The test, made by California-based Ellume, will sell for around $30 (€25) and the company plans to roll out three million units next month, and millions more in subsequent months.
Stephen Hahn, commissioner of the Food and Drug Administration, said the emergency use authorisation represented a "major milestone." "We are helping expand Americans' access to testing, reducing the burden on laboratories and test supplies, and giving Americans more testing options from the comfort and safety of their own homes," he said.
