Some rapid, at-home Covid-19 tests are being recalled due to a number of false positive results.

Ellume announced on their website that the company is voluntarily recalling specific lots of their tests.

The company said on their website, "there is an increased chance that tests from the affected lot numbers may give a false positive result. The voluntary recall is being taken after specific product lots reported false-positive test result rates higher than was observed in clinical testing."

The tests had been granted emergency use authorization from the U.S Food and Drug Administration back in December. The tests were the first COVID-19 tests that could be used completely at home without a prescription.

Ellume said they are removing the affected product from store shelves and working with the FDA. The company is advising consumers to visit www.ellumecovidtest.com/return to check whether their product is part of the affected lots and if affected, to receive further instructions.

The company said, consumers who attempt to use the affected tests will be notified in the Ellume COVID-19 Home Test app that the test has been recalled. Consumers can then receive a product replacement.

In a statement, the company said, "We offer our sincere apologies for the stress or difficulties people may have experienced due to a false positive result. We have and will continue to work diligently to ensure test accuracy, in all cases."

According to the company's website,  their at-home tests are available at Amazon, CVS, Target, and Walmart.
