NCT03344887

Brief Summary

The iTADS trial will test an important blood donor characteristic - donor sex - to see whether male donor blood leads to a greater benefit for transfusion recipients compared to female donor blood. The trial will help determine how the investigators can tailor the selection of blood donors based on donor characteristics (e.g. sex) to further improve the safety and optimize the clinical benefit of blood products in Canada.
