Abstract
ABSTRACT Group O red blood cells (RBCs) express the highest amount of H antigen of any other blood group and are therefore expected to demonstrate strong reactivity when tested with Ulex europaeus anti-H lectin, unless the RBCs are from individuals possessing the Bombay or para-Bombay phenotypes. We report several examples of group O RBCs not belonging to the aforementioned groups that consistently produced weak reactions with quality-controlled Ulex europaeus lectin.
