In the method for the preparation of bicarbonate-containing hemodialysis fluids of individually adaptable compositions according to specific therapeutic requirements of patients a combination of a quantitatively greatly predominating basic concentrate of uniform standard composition is applied in conjunction with an individually selected additional or individual concentrate. The basic concentrate, mainly consisting of sodium chloride and sodium bicarbonate, supplies to the dialysis fluid a sodium concentration at or slightly below the lower limit of the physiological range, whereas the individual concentrate supplies the complementary concentration of sodium up to an individually selected physiological level as well as salts of potassium, calcium, and magnesium and also glucose in individually adapted concentrations. The individual concentrate is a 120- to 250-fold liquid concentrate, resulting in an easy to handle quantity of typically one liter for one dialysis treatment.

A method for preparing a bicarbonate hemodialysis fluid adapted to the individual physiological requirements of a patient in need of dialysis, comprising the steps: i) providing a primary concentrate (a) of fixed concentration and not tailored to the individual physiological requirements of the patient, ii) providing a plurality of additional concentrates (b) having differing compositions, iii) selecting a concentrate (b) according to the individual physiological requirements of the patient, and iv) diluting concentrate (a) and the selected concentrate (b) with water to obtain said hemodialysis fluid; wherein primary concentrate (a) supplies sodium ions between 120 and 135 mmol/liter based on the hemodialysis fluid, 100% of the bicarbonate and has a molar ratio of bicarbonate/sodium of 0.3 or less; and concentrate (b) is a 120 to 250-fold liquid concentrate that supplies additional sodium in an amount up to 25 mmol/l, 0-5 mmol/l potassium, 0.3-2.5 mmol/l calcium and 0-1.2 mmol/l magnesium ions, all concentrations based on said hemodialysis fluid, representing the total quantities of calcium and magnesium ions in the hemodialysis fluid.
