A blood coagulation accelerator that excels in long-term storage stability at ordinary temperature or even under harsher conditions, being capable of stably exerting enhanced blood coagulation performance over a prolonged period of time; and a vessel for blood test in which this blood coagulation accelerator is accommodated. There is provided a blood coagulation accelerator characterized by being composed of an enzyme capable of, in peptide chains, hydrolyzing bonds between arginine and any amino acid residue and/or bonds between lysine and any amino acid residue, a matter resulting from deactivation of this enzyme by exposure to radiation, and β-alanine. |
