FDA approves new at-home coronavirus test kits

Driving the news: The Food and Drug Administration announced Tuesday that it granted emergency authorization for LabCorp's first at-home coronavirus test, CBS News reports.

• The test is a nasal swab kit and will cost $119, though buyers must complete an eligibility survey before receiving one.
• It will not be available in New York, New Jersey, Maryland and Rhode Island because they have regulations against people initiating their own tests, according to CBS.

What they're saying: Hahn told CBS that health care workers and first responders will have first access to the test when it goes on sale.

• Hahn added that the test is as effective as those administered in a doctor’s office.
• "With this action, there is now a convenient and reliable option for patient sample collection from the comfort and safety of their home," he said in a statement.

The big picture: The United States had conducted more than 4 million tests as of Wednesday morning, according to Johns Hopkins University data.

• The country has tested an average of 146,000 people per day so far in April, according to the COVID Tracking Project.
• Harvard University researchers suggest that the U.S. cannot reopen its economy unless it triples the number of daily tests, the New York Times reports.
