Abstract:
1. A serum or plasma separating composition containing: a liquid resin component having a partition wall-forming capability; a hydrophilic inorganic powder; a hydrophobic inorganic powder; and an organic compound serving as a thixotropy enhancer, wherein the organic compound is a polyalkylene glycol and/or a derivative thereof and is made of at least one type of polymer selected from the group consisting of: 1) a homopolymer of a single type of monomer selected from C 2) a random copolymer, an altering copolymer, or a periodic copolymer of two or more types of monomers selected from C 3) a block copolymer of two or more types of monomers selected from C 4) a graft copolymer of at least one type of polymer of the polymers 1) to 3), the polyalkylene glycol and/or the derivative thereof has a number average molecular weight of 500 to 100000, both inclusive, and the content of the polyalkylene glycol and/or the derivative thereof in the total amount of the serum or plasma separating composition is 0.2% to 5% by weight, both inclusive.
