FDA warns of bacterial contamination in some at-home COVID tests.

The FDA has recalled over half a million "Pilot COVID-19 At-Home Tests" from Roche and SD Biosensor due to concerns over bacterial contamination in the liquid buffer solution. The recalled tests were distributed to CVS and Amazon, but not through federal government testing programs. The bacteria found in the tests can lead to potentially dangerous infections, especially in people with compromised immune systems. So far, no injuries or deaths have been reported, but people who have already used the tests may have received false positive or false negative results. Roche and SD Biosensor are cooperating with the FDA in their investigation.
