Objective To investigate necessity of the further processing for adsorptive resin material. Methods According to GB/T 16886.4, coagulation tests, haematology tests, in vitro spontaneous platelet-adhesion test and complement activation tests were conducted respectively to assess the in vitro blood compatibility of adsorptive resin material. Results In comparison with polypropylene, he adsorptive resin material appears to be a very slight activator to the endogenous blood coagulation system, it can inhibite the exogenous blood coagulation system very significantly(P<0.01), it can adhere to fibrinogen, red blood cells, reticulocytes very significantly(P<0.01), and platelet significantly(P<0.05). The adsorptive resin material is also revealed to be a very significant activator(P<0.01) to the complement system. Conclusions The in vitro blood compatibility assessment witnesses that it is very necessary for the adsorptive resin material to go through the certain special processing(such as the surface modification and the microencapsulation technology, etc) before its application to human being.%目的研究吸附树脂原料进行进一步加工处理的必要性。方法依据GB/T 16886.4的有关规定，通过凝血试验，血液学试验，体外自发性血小板粘附试验及补体激活试验对吸附树脂原料进行体外血液相容性评价。结果与聚丙烯相比较，吸附树脂原料是内源性凝血系统的极轻微激活剂，对外源性凝血系统有极显著性抑制作用（P＜0.01），对纤维蛋白原、红细胞及网织红细胞呈现极显著性粘附作用（P＜0.01），对血小板有显著性粘附作用（P＜0.05），吸附树脂原料同时也是补体系统的极显著性激活剂（P＜0.01）。结论体外血液相容性评价表明：吸附树脂原料必需经过特定的工艺（如表面修饰、微囊化技术等）才可用于人体。
