Antibody test makes picking COVID-19 plasma donors easier

Researchers report using a new and more accurate way of testing for antibodies against SARS CoV-2 in recovered patients as a means to characterize the potential effectiveness of their convalescent plasma for donation to sick patients. …  “It appears that recovered patients have different antibodies that target COVID-19. This tool to comprehensively measure these antibodies will allow physicians to choose the most effective donors for convalescent plasma therapy,” says Philip Felgner, the director of the Vaccine R&D Center at the University of California, Irvine School of Medicine.
