PROBLEM TO BE SOLVED: To provide a reagent for sufficiently extending a blood coagulation time, and correctly and sensitively implementing a blood coagulation ability examination without a reduction in the optical change quantity. SOLUTION: A blood coagulation ability measuring specimen diluting liquid contains a blood coagulation time extension agent in a blood coagulation reaction which contains an active ingredient as a benzamidine or its derivative. The blood coagulation ability measuring specimen diluting liquid is a fibrinogen measuring specimen diluting liquid. A method for adjusting the optical change quantity in the blood coagulation reaction is characterized so as to combine the blood coagulation time extension agent in the blood coagulation reaction which contains the active ingredient as the benzamidine or its derivative and the blood coagulation time extension agent in the blood coagulation reaction which is selected from a halide salt and a propionic acid salt of an alkali metal or an alkali earth metal.
