The US government’s free at-home Covid-19 test program will be suspended Friday, according to the Administration for Strategic Preparedness and Response.

Since November, residential households in the US have been able to submit an order through Covidtests.gov for four individual rapid antigen tests. All orders placed on or before Friday will be fulfilled, according to ASPR, an operating division of the US Department of Health and Human Services.

“ASPR has delivered over 1.8 billion free COVID-19 tests to the American people through COVIDTests.gov and direct distribution pathways and will continue distributing millions of tests per week to long-term care facilities, food banks, health centers, and schools,” an ASPR spokesperson said in a statement Tuesday.
