A hemolytic anti-LKE associated with a rare LKE-negative, 'weak P' red blood cell phenotype: alloanti-LKE and alloanti-P recognize galactosylgloboside and monosialogalactosylgloboside (LKE) antigens

摘要

BackgroundWeak P is a rare red blood cell (RBC) phenotype, characterized by a global decrease in P-k and P antigens. We now describe a second weak P individual who also typed LKE-negative (LKE-N) and possessed a clinically significant anti-LKE.
