As the number of COVID-19 cases have continued to rise, the American Red Cross has also seen a growing number of COVID-19 antibody test screens from blood, platelet, and plasma donors. The screening efforts provide insight into whether donors have been exposed to this coronavirus throughout the pandemic, while also enabling the distribution of convalescent plasma to ensure patients have access to lifesaving treatment.
Since the Red Cross started antibody testing on June 15, 2020, the data has been incorporated into a new set of interactive maps that depict regional, statewide, and residential statistics on the number of healthy, donors that have shown COVID-19 antibodies in each of the U.S.’s four U.S. census regions.
These maps showing antibody results from healthy individuals are not representative of the general population. They focus only on results from Red Cross blood donors. In addition, COVID-19 convalescent plasma donors are not included in these maps. Also, the antibody test is not a diagnostic test – a reactive result on a donation from a healthy individual does not indicate current infection or presence of the virus.
