FDA recalls over 500K COVID tests due to bacterial contamination risk.

The FDA has recalled over 500,000 COVID-19 tests due to concerns of bacterial contamination. The recalled SD Biosensor, Inc. Pilot COVID-19 At-Home Tests were distributed by Roche Diagnostics, and the FDA has "significant concerns" with the test kit's liquid solution. The agency warns that direct contact with the solution could pose safety risks and compromise the test's accuracy. Consumers and healthcare providers should discard the recalled tests, and patients who took one of the recalled tests in the past two weeks should be retested with an FDA-approved test.
