A new approach to neocyte transfusion: Preliminary report

A method has been developed using phthalate oils to quality control units of young red cells (neocytes). Neocytes prepared by the NEOCEL system have a mean young red cell enrichment of 90% with only 3.4% less than 80%. Neocytes prepared in a Wood cell processor have an average enrichment of 81 % with 27% less than 75%. Based on a 12 month period, the patients as a group have received an average of 14% fewer transfusions and an 18% decrease in red cells per kg/yr as compared to frozen red cells.
