Cord blood donations are a valuable medical resource that can treat over 80 diseases, including leukemia, lymphoma, and genetic disorders. Unlike bone marrow, cord blood is collected after birth from the umbilical cord and placenta, posing no risk to mother or baby. The blood is rich in hematopoietic stem cells, which can regenerate healthy blood and immune cells.
How Cord Blood Donation Works
After a baby is born, the umbilical cord is clamped and cut. The remaining blood in the cord and placenta is collected using a sterile needle and bag. This process takes only a few minutes and does not interfere with delivery or bonding. The collected blood is then transported to a cord blood bank, where it is tested, processed, and cryogenically frozen for future use.
According to Health Canada, the donation process is free for donors, and the blood can be stored for years. Public cord blood banks in Canada, such as the Canadian Blood Services Cord Blood Bank, accept donations from consenting mothers at participating hospitals. The donated blood is listed on international registries, making it available to patients worldwide.
A Local Mom's Perspective
Ottawa mother Sarah Thompson donated her son's cord blood in 2025. She said it was an easy choice. “I learned about cord blood donation during my prenatal classes and knew I wanted to help others,” Thompson said. “The process was simple, and it felt good knowing that something that would otherwise be discarded could save a life.”
Thompson's donation was accepted by the Canadian Blood Services Cord Blood Bank. She encourages other parents to consider donating. “It's a small step that can have a huge impact,” she added.
Eligibility and Registration
To donate cord blood, mothers must meet health criteria and deliver at a participating hospital. Donors must be at least 18 years old, have a healthy pregnancy, and have no history of certain diseases. Consent is obtained before labour, and the collection is done by trained staff.
Canadian Blood Services aims to expand its cord blood program to more hospitals across Canada. Currently, donations are accepted at select sites in Ontario, Alberta, and British Columbia. The organization also provides information on its website for interested parents.
Impact of Cord Blood Transplants
Cord blood transplants are used when a patient needs a stem cell transplant but does not have a matching bone marrow donor. Because cord blood stem cells are less mature, they require less perfect matching, making them a valuable option for diverse populations. According to the Canadian Cancer Society, cord blood transplants have saved thousands of lives worldwide.
Dr. Jennifer Lee, a hematologist at The Ottawa Hospital, explains: “Cord blood is a crucial resource for patients with blood cancers and genetic disorders. It offers a chance for a cure when other options are limited.”
