WebMar 18, 2024 · One method to determine if alloantibody is demonstrable in the presence of autoantibody is an autoadsorption. The use of enzyme or ZZAP-treated autologous cells facilitates the removal of autoantibody by removing membrane structures that interfere with antibody binding. WebPEG is a water soluble polymer that “eliminates” water allowing RBCs to get closer together. PEG is more effective than LISS or albumin in detecting weak antibodies. PEG is added after the immediate spin (IS) and incubated. There is no 37C interpretation when using PEG because centrifuging RBCs with added PEG can cause false positives.
