The Biden administration has made a $231.8 million deal with an Australian company to boost availability of the first at-home rapid test for the coronavirus which causes COVID-19 that is available without a prescription. The test, made by Ellume, can send results to a smartphone within 15 minutes of receiving a sample. The FDA gave emergency authorization to Ellume's rapid test in December, after it showed 96% accuracy in a U.S. clinical study.
