📖 Reference information: Blood chimerism is a condition in which two populations of red blood cells, differing in blood group or other antigens, are present in the bloodstream of a single organism. This phenomenon can arise as a result of cell exchange between fetuses in multiple pregnancies, after hematopoietic stem cell transplantation, or blood transfusion. The presence of chimeric populations is important to consider when interpreting laboratory results and selecting donor blood.
