Date Issued: October 5, 2021
The U.S. Food and Drug Administration (FDA) is alerting test users, caregivers, health care personnel, and the public of the potential for false positive results with certain lots of the Ellume COVID-19 Home Test, due to a recently identified manufacturing issue. For these tests, a “false positive” is a test result that indicates that a person has the virus when they do not actually have it. Negative results do not appear to be affected by the manufacturing issue.
The FDA is working closely with Ellume to assess the company’s additional manufacturing checks and other corrective steps to help ensure that the issue is resolved.
A complete list of affected Ellume COVID-19 Home Tests can be found on Ellume’s website.
Recommendations for Test Users and Caregivers
- Check if your Ellume COVID-19 Home Test is included in Ellume’s product recall by comparing the lot number on the test carton to the lot numbers on Ellume’s website.
- Contact your health care provider, urgent care facility, or other COVID-19 testing site and request a COVID-19 molecular diagnostic test if you received a positive test result with one of the affected lots of the Ellume COVID-19 Home Test in the last two weeks and have not already had a follow-up molecular diagnostic test to confirm the positive test result.
- Contact your health care provider, urgent care facility, or other COVID-19 testing site if:
- You received a positive test result using one of the affected lots of the Ellume COVID-19 Home Test more than two weeks ago, and
- You did not receive a positive result from a different COVID-19 test at the time of the original Ellume positive test result. A health care provider can help you decide what next steps you should take. You should not assume that you had COVID-19 or have immunity to COVID-19. You should continue to take recommended precautions, including vaccination, to avoid COVID-19 infection, following the Centers for Disease Control and Prevention’s guidelines.
- If you have an unused Ellume COVID-19 Home Test from an affected lot, use the Ellume COVID-19 Home Test App or follow the directions on Ellume’s website to request a product replacement.
Recommendations for Health Care Personnel
Review the Recommendations for Test Users and Caregivers with patients who used the affected tests and received a positive result.
The Ellume COVID-19 Home Test is an antigen test that detects proteins from the SARS-CoV-2 virus from a nasal sample in people 2 years of age and older. The Ellume COVID-19 Home Test is for people with or without COVID-19 symptoms.
The FDA issued an Emergency Use Authorization (EUA) to permit emergency use of the Ellume COVID-19 Home Test on December 15, 2020 and granted a revision to the EUA on February 11, 2021.
The FDA regularly monitors the post-authorization use of tests, including reports of problems with test performance or results, and is providing this information to help educate patients, caregivers, and health care providers.
The FDA is continuing to work with Ellume to assess the company’s additional manufacturing checks and other corrective steps to address the reason for the manufacturing issue and help ensure that it is resolved.
The FDA will keep the public informed if significant new information becomes available.
