Health Department Announces New Schedule At The COVID Alstom Testing Site Expand The Hamilton County Health Departmentâs COVID testing site at Alstom will no longer operate on Sundays, beginning January 24. The site will continue operations 6 days a week from Monday through Saturday, 10:00AM-2:30PM. As always, testing continues to be free and no appointment is necessary. âThere has been a steady decrease in the demand for testing,â said Health Department Administrator Becky Barnes, âand an increase in both the demand and supply of vaccine. Therefore, we are making changes to accommodate this new phase of pandemic response and will redirect staff from our testing site to our vaccination sites on Sundays. We want to assure the community that we will continue to offer free testing as long as there is a need.â
