The CDC Operation Expanded Testing (OpET) program provides access to free COVID-19 PCR tests for assisted living residents and staff, through December 31, 2022. The program provides specimen collection supplies, shipping materials, laboratory testing, and results reporting, and providers may receive up to a four-week supply at a time.
Be sure to read the FAQs to learn how the program works. The FAQs refer to schools in a few places and don't mention long-term care. However, the program is designed for other "congregate settings" which include assisted living facility residents and staff.
