PROBLEM TO BE SOLVED: To coagulate blood in a short time and to enable separation of blood serum containing no blood corpuscles without using a centrifugal separator by shaking a blood sampling tube to dissolve a specific blood corpuscle coagulant and a blood coagulation accelerator in blood, coagulating the blood, and moving a porous plate from the liquid level of the coagulated blood in the direction of the bottom of the tube. SOLUTION: Blood is sampled into a blood sampling tube 2 in which a blood corpuscle coagulant and a blood coagulation accelerator are placed, and the blood sampling tube 2 is shaken to dissolve the blood corpuscle coagulant and the blood coagulation accelerator in the blood. Then it is left in a stationary state to coagulate the blood. A porous plate 5 of smaller diameter than the inner diameter of the blood sampling tube 2 is moved from the liquid level of the blood in the direction of the bottom of the tube 2 to remove blood corpuscles floating in serum 8 to separate the serum 8. A blood corpuscles coagulant to be used has no special limitation, and it is possible to name compounds with amino groups of molecular weight 450 or more, i.e., synthetic high-molecular compounds such as polyacrylamide, low-molecular compounds such as a polyamine acid with a constituent component of a basic amino acid such as poly-L-lysine, vancomycin.
