A and B antigen levels acquired by group O donor‐derived erythrocytes following <scp>ABO</scp>‐non‐identical transfusion or minor <scp>ABO</scp>‐incompatible haematopoietic stem cell transplantation

Abstract

The in vivo conversion of donor-derived blood group O RBC to ABO subgroup-like RBC after transfusion or minor ABO-incompatible HSCT raises the question of appropriate component selection. Based on these data, AB plasma should be transfused following ABO-incompatible HSCT.
