Abstract

ABO discrepancies due to mixed-field agglutination are commonly seen with subgroups of A or B and ABOincompatible RBC transfusion in routine immunohematology laboratory. We report a 20 year old male with minor ABO and Rh D mismatched hematopoietic stem cell transplantation presenting with blood group chimerism. Column agglutination technique (CAT) had advantages in detecting mixed field agglutination than other techniques used in routine blood grouping
