Practical Info The GDG made a r ecommendation against using c onvalescent plasma in those with se vere or critical COVID-19 outside the context of a clinical trial and a str ong recommendation against using c onvalescent plasma for treatment of patients with nonsevere COVID-19. Given this, w e will no t go into detail regarding the many practical issues related to c onvalescent plasma including but not limited to: identification and recruitment of potential donors, collection of plasma, storage and distribution o f plasma, and infusion of convalescent plasma into recipients.

Resources and other considerations Acceptability and feasibility The GDG no ted that convalescent plasma use is associa ted with significant resource requirements including identification of potential donors, testing o f donors to ensur e adequate titres of anti-SARS-CoV-2 antibodies, collection of donor plasma, storage of plasma, transportation of plasma to r ecipient location, and administration of plasma. Also, this process is c ostly and time-consuming. Although blood transfusion is ac ceptable to most, there is a subse t of the popula tion that will not accept allogenic blood transfusion. There are also regulatory challenges in most jurisdictions r elated to blood pr oduct transfusion.
