Allogeneic adsorptions: a comparison of the traditional method with a modified PEG adsorption method.

The purpose of this study is to demonstrate the benefits of enhancing adsorptions with PEG. Allogeneic adsorptions were performed on 20 patient samples containing warm reactive autoantibodies with two volumes of adsorbing RBCs; results using unenhanced adsorptions were compared with those using PEG-enhanced adsorptions and with using untreated adsorbing RBCs and ficin-treated adsorbing RBCs. Two volumes of adsorbing RBCs, one volume of serum, and one volume of PEG were used.
