Free at-home COVID-19 testing kits will be made available to American households through a government website starting Jan. 19 under a new Biden administration initiative.

Households will be able to order four tests at a time online at The tests are expected to ship typically “within 7-12 days of ordering,” according to a federally issued fact sheet.

The federal government has 420 million tests under contract and tens of millions in its possession already, according to a Politico report. Officials are sill finalizing contracts for the remaining 80 million tests out of an initial order of 500 million.

“We anticipate the first tests going out at the end of this month, with the remaining tests going out over the next 60 days,” Health and Human Services Assistant Secretary for Preparedness and Response Dawn O’Connell told the Senate HELP Committee during a hearing on the pandemic response last week.

The total cost of the effort to buy and distribute the testing kits is expected to be around $4 billion.

The South Carolina Department of Health and Environmental Control’s (DHEC) offices are closed for Martin Luther King Jr. Day. Test results from Jan. 15-18 will be reported Tuesday. A total of 65,721 test results were reported Jan. 14, keeping up with high testing numbers in the wake of the Christmas and New Year’s holiday.
