RBC T activation and hemolysis in a neonatal intensive care population: implications for transfusion practice.

Background: Reports of transfusion-associated hemolysis in infants with T-activated RBCs have led to the suggestion that infants should be screened and provided with low-titer anti-T blood components. T-activated RBCs react with the lectins Arachis hypogea and Glycine soja; variants of T (Th and Tx) and Tk also react with A. hypogea, but not G.
