The LOS Blood Donor Registry is a groundbreaking project designed to monitor the long-term health effects of regular blood donation over a minimum of 30 years. The one-pager highlights the importance of this registry in aligning with WHO guidelines for blood donation safety and long-term donor health monitoring.

Key features of the LOS Blood Donor Registry include:

• Addressing critical uncertainties in donor health, such as iron depletion, cancer risk, cardiovascular health, and mental health effects
• Empowering donors through health monitoring and improved medical care
• Benefiting various stakeholders including medical staff, scientists, policymakers, and donors themselves
• Ensuring user-friendliness, data security, and accessibility

Following the successful development of the registry for transfusion patients, the project is currently in a multidisciplinary stakeholder engagement phase for the donor registry. The team is collaborating with various experts and organizations to define key data elements. The implementation of the LOS Blood Donor Registry is planned for 2025, marking a significant step forward in blood donation research and donor care.
