FDA Clears First Rapid At-Home COVID Test

The US Food and Drug Administration (FDA) issued an emergency use authorization for the first at-home COVID-19 diagnostic test, which provides results in 30 minutes or less.

The COVID-19 prescription All-In-One Test Kit (Lucira Health) is a molecular, single-use test that detects SARS-CoV-2 using self-collected nasal swab samples in people aged 14 years and older who are suspected of having COVID-19 by their healthcare provider.

The test is also authorized for use in doctor's offices, hospitals, urgent care centers, and emergency departments for patients of all ages. However, samples must be collected by a healthcare provider when the test is used in these care settings for patients younger than 14 years. The Lucira test is currently available by prescription only.

"The FDA continues to demonstrate its unprecedented speed in response to the pandemic. While COVID-19 diagnostic tests have been authorized for at-home collection, this is the first that can be fully self-administered and provide results at home," FDA Commissioner Stephen M. Hahn, MD, said in a news release.

"This new testing option is an important diagnostic advancement to address the pandemic and reduce the public burden of disease transmission. [This] action underscores the FDA's ongoing commitment to expand access to COVID-19 testing," said Hahn.

Rapid and Highly Accurate

The test kit includes the test device, sample vial, swab, and simple instructions. Two AA batteries are inserted in the device, and the sample vial is placed in the test unit.

After this has been done, the user opens the test swab packet and rotates the swab in each nostril five times. The swab is then stirred in the sample vial. It is then pressed down in the test unit to start the test. The "ready" light then blinks. Within 30 minutes, a "positive" or "negative" green light is illuminated.

In a community sample, in which the test was compared with an FDA-approved, high-sensitivity SARS-CoV-2 test, the Lucira test achieved a 94% positive percent agreement and a 98% negative percent agreement. After exclusion of samples with very low levels of virus that possibly no longer reflected active infection, Lucira's test achieved 100% positive percent agreement, according to the company's website.

The FDA said individuals with positive results should self-isolate and seek additional care from their healthcare provider. Those who test negative but who experience COVID-like symptoms should follow up with their healthcare provider, inasmuch as negative results do not preclude a person's being infected with SARS-CoV-2.

While Lucira Health scales up manufacturing capabilities, its COVID-19 test kit will initially be available on a limited basis in point-of-care settings and healthcare networks that prescribe the test for patients to use at home. The company anticipates that the test will cost around $50.

Prescribing healthcare providers are required to report all Lucira test results from individuals to their relevant public health authorities in accordance with local, state, and federal requirements. The company has developed box labeling, quick reference instructions, and healthcare provider instructions to assist with reporting.

Authorization for a complete at-home test is "a significant step toward FDA's nationwide response to COVID-19," said Jeff Shuren, MD, JD, director of the FDA's Center for Devices and Radiological Health, in the news release.

"A test that can be fully administered entirely outside of a lab or healthcare setting has always been a major priority for the FDA to address the pandemic," Shuren said. "Now, more Americans who may have COVID-19 will be able to take immediate action, based on their results, to protect themselves and those around them."
