COVID-19 and transfusion medicine
This repository aims to support Canadian transfusion medicine health care professionals during the COVID-19 pandemic. It will be updated regularly as new information is available. In addition, the public and donors can learn more about how Canadian Blood Services is responding to COVID-19 by visiting blood.ca/covid-19.
Blood products inventory management
The National Emergency Blood Management Committee meets regularly to review the supply of blood components and products during the pandemic and make inventory advisories.

FAQ for health professionals working with blood products
Health-care workers who handle fresh blood components from Canadian Blood Services (i.e., red blood cells, platelets, plasma) may have questions about whether accidental exposure to these products puts them at risk for COVID-19. Read our FAQ that summarizes evidence supporting the view that the SARS-CoV-2 virus is not transmitted through blood and also provides links to other related guidance documents.
Hospital-based transfusion services during COVID-19
Effects of the COVID-19 pandemic on supply and use of blood for transfusion: Stanworth et al. (July 2020, The Lancet Haematology). COVID-19 has brought major implications for blood transfusion practices: uncertain demand patterns, reduced donations and loss of staff. This paper synthesizes studies that address the transfusion chain and provide guidance during times of potential or actual shortage. Dr. Mindy Goldman, Medical Director at Canadian Blood Services, is one of the study’s authors. For more about the study, visit the R.E.D. blog.
An article by Yazer et al. (May 2020, Vox Sanguinis) surveyed 12 centres from around the world (including Canada) about how hospital-based transfusion services have responded during COVID-19, including sample handling, pre-transfusion testing and issuing of blood products. See Table 2 in the article for a summary of respondents’ answers.

Treatment of COVID-19 patients
Intravenous Immune Globulin (IVIG)
Currently, IVIG is not available for patients with COVID-19 and there is no evidence to suggest it would be an effective treatment. Given limited supplies of IVIG, its use to treat COVID-19 patients would rapidly deplete current stocks and limit access to other patients with diagnoses where IVIG is proven effective.
For information see “Fact Sheet on Convalescent Plasma and Intravenous Immune Globulin (IVIG) for Treatment of COVID-19 in Canada” published by National Advisory Committee on Blood and Blood Products on March 31, 2020.
All three national clinical trials examining COVID-19 convalescent plasma as a potential treatment option for COVID-19 patients (CONCOR-1, CONCOR-KIDs, REMAP-CAP) have discontinued patient enrolment. On Friday, January 29, 2021, the CONCOR-1 trial's independent data safety monitoring committee determined that the study is unlikely to demonstrate a benefit of convalescent plasma even if more patients are enrolled. The CONCOR-1 study team is in the process of completing the follow-up data for all enrolled patients and will release the final study results once the complete data set is available.
To learn more about Canadian Blood Services’ contributions to CONCOR-1 see below.
- February 3, 2021: Canadian Blood Services suspends convalescent plasma collection following decision by study team to stop patient enrolment. See trial update at concor1.ca.
- April 16, 2020: Canadian Blood Services Chief Scientist, Dana Devine spoke with The Agenda to discuss the clinical trial.
- April 2, 2020: Canadian Blood Services announces that it is actively working with Health Canada and the international research community as part of a global effort to determine if convalescent plasma could effectively treat COVID-19. Canadian Blood Services will contribute by collecting and preparing plasma from fully recovered COVID-19 patients. Canadian physicians caring for patients with COVID-19 will have access to the convalescent plasma in the context of the clinical trial.
