WASHINGTON (AP) - 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 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.

Allowing people to self-swab at home would help reduce infection risks for front-line health care workers and help conserve protective gear.

For the home test, people are initially screened with an online questionnaire. If authorized by a physician, LabCorp will ship a testing kit to their home. The kit includes cotton swabs, a collection tube, an insulated pouch and box to ship the specimen back to LabCorp. To take a sample, a cotton swab is swirled in each nostril. The test results are posted to a secure company website.

The company will make the test available in the coming weeks. Each kit will cost $119.

Initially, the Food and Drug Administration required health care workers to collect all samples from potential coronavirus patients.

LabCorp’s test is the first that allows it to be done at home without supervision.

FDA Commissioner Stephen Hahn said the agency authorized the self-swab test based on data showing it is “as safe and accurate as sample collection at a doctor’s office, hospital or other testing site.”
