Until more is known about protective immunity, serology results should not be used to make staffing decisions or decisions regarding the need for PPE.
LabCorp's chief medical officer, Brian Caveney, said interest in antibody testing is coming from companies in coronavirus hotspots, such as NY, while other areas with fewer COVID-19 cases see diagnostic testing as more important.
Fast Pace Urgent Health Care in Algood is offering COVID-19 antibody testing. "If we're looking for absolutes, it's not going to give us absolutes. The test will only be available online via our online doctor service and will not be available in our stores".
