WASHINGTON — U.S. health regulators on Tuesday OK’d the first coronavirus test that allows people to collect their own sample at home, a new approach that could help expand testing options in most states.

The test from LabCorp LH, +0.50% will initially only be available to health care workers and first responders under a doctor’s orders. The sample will still have to be shipped for processing back to LabCorp, which operates diagnostic labs throughout the U.S.
