The Food and Drug Administration announced in a post Tuesday night it has issued an emergency use authorization for the first COVID-19 test for self-testing at home — and it returns rapid results.

The big picture: Lucira Health developed the molecular single use test. "In 30 minutes or less, the results can be read directly from the test unit's light-up display that shows whether a person is positive or negative for the SARS-CoV-2," the virus that causes COVID-19, the FDA said in a statement.

Of note: The test kit is currently available by prescription only.
