FDA OKs first test at home for flu, COVID

- By Christina Jewett and Emily Anthes

The Food and Drug Administra­tion has issued an emergency authorizat­ion for the first over-thecounter, at-home combinatio­n flu and COVID test, just two days after the company that makes the test announced that it had filed for bankruptcy protection based, in part, on the agency's lengthy approval timeline.

The single-use test works with a self-collected nasal swab and provides a result in about 30 minutes, according to the FDA. The test is meant to be used by people 14 and older, or by an adult collecting a sample from someone age 2 or older.

The test's developer, Lucira Health, based in California's Bay Area, announced its bankruptcy plan Wednesday, noting that it had expected its emergency use authorizat­ion for the test in August, before the onslaught of the flu season. The company said the agency's authorizat­ion process “became protracted” and that it had high expenditur­es as it moved forward with manufactur­ing the combinatio­n tests.

Without revenue that the company expected from projected sales of the tests during this year's flu season, Lucira decided that it would pursue a sale of its business but continue operations to serve customers, according to a news release. The bankruptcy plan was reported earlier in the Wall Street Journal.

In a statement issued Friday, Dr. Jeff Shuren, director of the FDA's device division, called the test “a major milestone in bringing greater consumer access to diagnostic tests that can be performed entirely at home.”

But even though public health experts and scientists welcomed the test authorizat­ion, it remained unclear when such a combined test would be widely available for sale to consumers. And that uncertaint­y compounded concerns that others have voiced about the Biden administra­tion's plans to end the coronaviru­s public health emergency in May, which could complicate access to testing.

People with private insurance and those on Medicare, who have been eligible for eight free athome tests per month, may have to pay out of pocket for the tests once the emergency ends.

The combinatio­n test correctly identified 99 percent of negative and 90 percent of positive flu A samples, according to the FDA. It also detected 100 percent of the negative and 88 percent of the positive COVID samples. The agency said it expected the company to continue to test on the flu B strain, which was not prevalent this year.

The product is a molecular test, which means it detects and amplifies the genetic material of the viruses, as a PCR test does. These tests are generally more sensitive than antigen tests, and at-home molecular tests have been more expensive than rapid antigen tests.

The new test will be the first of a series of combinatio­n diagnostic­s in different stages of developmen­t that will scan for multiple ailments at once, said Wilbur Lam, a pediatric hematologi­st and bioenginee­r at Emory University.
