What happens to donated blood?
Summary
Canadian Red Cross blood donor centres ensure blood safety through rigorous donor screening and advanced testing for infectious diseases. Practices are evolving to meet the challenges of declining donor numbers and the classification of blood as a drug.
Area of Science:
- Transfusion Medicine
- Public Health
- Biotechnology
Background:
- Blood donor centres are essential for public health, providing critical blood products.
- The Canadian Red Cross Society adheres to standard operating procedures for blood collection and processing.
- Declining donor numbers present a significant challenge to blood supply stability.
Purpose of the Study:
- To outline the standard operating procedures for blood donor centres.
- To detail the donor recruitment and screening processes.
- To describe the blood testing and component processing methods.
Main Methods:
- Donor registration with permanent identification numbers.
- Health and high-risk activity questionnaires for donor eligibility.
- Automated and confirmatory laboratory testing for infectious diseases (syphilis, hepatitis B/C, HIV, HTLV).
Main Results:
- Blood units undergo multi-stage screening for infectious agents.
- Reactive test results trigger confirmatory testing and donor notification.
- Negative test results allow for component breakdown and hospital distribution.
Conclusions:
- Blood donor centres implement comprehensive safety protocols.
- Continuous adaptation of practices is necessary due to evolving challenges.
- Blood is now recognized and managed as a pharmaceutical product.
