The blood collection and transfusion equipment with leukocyte filtration is used in the filtration of whole blood or red blood cell suspension. In vitro evaluation of hemocompatibility was conducted to ensure its safety when the product is used in clinic. Three major components of the product, the flexible pipeline, plastic blood bag and filtration membrane, were chosen for the samples, and the same parts from same type import products for the reference material. According to the GB/T 16886.4—2003 and the GB/T 14233.2—2005, three parameters of hemolysis, PTT and the blood platelet aggregation assay were tested. The experimental results showed that the hemolysis rates of the samples were below 5 per cent. There were no significant differences in the partial thromboplastin time and the platelet maximum aggregation rate between the samples and the reference materials (P>0.05). These results indicated that the blood collection and transfusion equipment with leukocyte filtration emerged little harmful effects on the blood ingredients and functions, and it was of good hemocompatibility.
