(Washington, DC) -- Free at-home COVID-19 tests are available starting today. Residential households in the U.S. can order one set of four rapid antigen COVID-19 tests by going to COVIDtests.gov . There's a button to click on that leads to a Postal Service page where folks can enter their information and order the tests. There's a limit of one order per address and they start shipping out in late January.
