As SC testing rates drop, sites slow down and drop hours As SC testing rates drop, sites slow down and drop hours By Chris Joseph | February 27, 2021 at 5:20 PM EST - Updated February 27 at 8:41 PM COLUMBIA, S.C. (WIS) - The demand for COVID-19 tests is dropping in South Carolina. Department of Health and Environmental Control data shows that on Feb. 25, clinics performed 33,499 tests. This represents a gradual decline since mid-January, and a sharp plunge from the testing peak on Feb. 3 with 64,054 tests. The drop in demand has translated to a reduction in hours at some testing sites. In February, Reid Chapel AME Church rolled back its COVID-19 testing site from Wednesday through Sunday to just Friday through Sunday.
