The Molecular Pathology Bridge laboratory sequences all positive COVID-19 specimens collected at MUSC for testing by real-time PCR that meet sequencing criteria. The results of sequencing will be shared with DHEC and GISAID for surveillance purposes. Individual results are not shared back with patients or physicians.
