The FDA continues its tight surveillance of rapid antigen tests for the COVID-19 pandemic and has issued three safety communications advising against the use of these tests thus far in the month of March. In each instance, the test is made by the manufacturer of name, but was not authorized in the U.S., making these misbranded products despite their legal use in other nations.

As the Omicron variant of COVID-19 sweeps across the globe, the Biden administration has announced a program to purchase 500 million rapid antigen tests to help slow the pandemic. The news comes at an especially critical time, given the increased transmissibility of the Omicron variant, but the promised volume is unlikely to be achieved by the first day of January 2022.

Advocates have continued to press for more widespread use of rapid antigen tests in the home as a primary instrument for returning to economic normalcy, and the FDA has granted an emergency use authorization (EUA) to Acon Laboratories Inc., of San Diego, for the company’s Flowflex rapid antigen test for at-home use. According to the FDA, Acon said the COVID-19 test will be produced at a rate of 200 million a month by February 2022, a clip that should go a long way toward restoring vigor to a lagging U.S. economy.
