Convalescent plasma is the liquid part of blood that is collected from patients who have recovered from the novel coronavirus disease,
COVID-19, caused by the virus SARS-CoV-2. If you have fully recovered from COVID-19, you may be able to help patients currently fighting the infection by donating your plasma.
COVID-19 patients develop antibodies in the blood against the virus. Antibodies are proteins that might help fight the infection.
Convalescent plasma is being investigated for the treatment of COVID-19 because there is no approved treatment for this disease and there is some information that suggests it might help some patients recover from COVID-19. Further investigation is still necessary to determine if convalescent plasma might shorten the duration of illness, reduce morbidity, or prevent death associated with COVID-19.
