RESUMEN
A survey of 19 large blood centers, each with an average annual collection of 158,889 units, was conducted to identify. current practices of management of red cell units that contain unexpected red cell antibodies. The routine antibody identification, distribution, and charge for such units varied widely among the 19 centers. In addition, although use of these units was low, costs were considerable. This survey can serve as a basis for other studies to arrive at cost-effective ways to manage such units.
RESUMEN
Reactivity of high-incidence antigens after glycine-EDTA treatment of red blood cells (RCs) to prepare artificial Ko RBCs was investigated. The treatment had little or no effect on Yta, JMH, Yka, Kna, and McCa. Hy antigen-positive-treated RBCs reacted less well with anti-Hy when compared to nontreated cells. Glycine-EDTA treatment to prepare Ko RBCs offers an advantage over AET treatment because it preserves some high-frequency antigens that AET treatment does not. Immunohematology 1994;10:64-65.
