The purpose of the present invention is to provide a dialysis agent A, which is able to set the total acetate ion content in the dialysate to a low value, excellent in storage stability of glucose, able to reduce the acetic acid odor, and able to suppress the corrosion of the dialysate delivery system and the dialysis machine, as well as to provide a two pack type dialysis agent utilizing the dialysis agent A.In the dialysis agent A used in the preparation of a bicarbonate dialysate, which is used as one part of a two pack type dialysis agent, it becomes possible to prepare a bicarbonate dialysate having the total acetate ion concentration of between 2 mEq/L or more and less than 6 mEq/L by allowing to include glucose, acetic acid and acetate salt and to satisfy the molar ratio of 1:0.5 to 2 of acetic acid and acetate salt, and include acetic acid and acetate salt in a total amount of between 2 mEq or more and less than 6 mEq in the dialysis agent A required to prepare 1 L of the bicarbonate dialysate. Moreover, according to the dialysis agent A, in addition to the excellent stability of glucose, it is possible to reduce the acetic acid odor, and furthermore possible to suppress the corrosion of the dialysate delivery system and the dialysis machine.
