Whole blood and red cells were stored using citrate-phosphate-dextrose (CPD) and citrate-phosphate-dextrose-adenine (CPDA-1) anticoagulants in polyvinylchloride bags made flexible with di-(2-ethylhexyl)phthalate (DEHP) or tri-(2-ethylhexyl)trimellitate (TOTM) plasticizers. After storage the posttransfusion viability of these cells was tested in autologous donors. Cells
