SouthPark and Concord Mills malls add rapid COVID testing sites. Here's what we know Catherine Muccigrosso, The Charlotte Observer Jan. 19—Rapid testing for the coronavirus will soon be available at two Charlotte-area malls. Medivolve, formerly named QuestCap, is opening COVID-19 testing labs for same-day testing results at SouthPark and Concord Mills malls, both managed by Simon. Each site can handle up to 150 tests a day. The cost is $59 for an antibody test, $99 for an antigen test and $179 for a PCR test usually required for travel. Antigen tests diagnose current viral infection while antibody tests show if a person already had the virus. The PCR test also shows if a person has the virus, and is considered among the most accurate tests.
