    • Provided is a blood separating agent that can form an excellent partition wall in an intermediate layer between clot and serum or between blood cell components and plasma even under low-temperature centrifugation conditions, is less likely to form crevices in the partition wall, is less likely to have any effect on test values, and offers stable performance even after long-term storage. The blood separating agent contains: a polymer for the blood separating agent which is composed of a (meth)acrylic acid ester-based polymer and has a viscosity of 10 to 200 Pa·s at 25° C. and a ratio of viscosity at 15° C. to viscosity at 25° C. of below 4.6; an inorganic powder; and a polyalkylene glycol having a number average molecular weight of 700 or more, wherein the polyalkylene glycol is mixed at a concentration of 5% by weight or less of the total weight of the blood separating agent.
    • 提供了即使在低温离心条件下也可以在凝块和血清之间或血细胞成分和血浆之间的中间层中形成优异的分隔壁的血液分离剂,不太可能在分隔壁中形成裂缝 对测试值有任何影响,即使在长期存储后也能提供稳定的性能。 血液分离剂含有:由(甲基)丙烯酸酯系聚合物构成的血液分离剂用聚合物,25℃下的粘度为10〜200Pa·s,粘度为15 ℃至25℃的粘度低于4.6; 无机粉末; 和数均分子量为700以上的聚亚烷基二醇,其中所述聚亚烷基二醇以所述血液分离剂总重量的5重量%以下的浓度混合。
