Dialysis fluid contains the same concentration of useful substances that can be found in normal... what?

Dialysis fluid, or dialysate, is designed to have a similar concentration of useful substances typically found in normal plasma to create a balanced environment in the dialysis process. This helps facilitate the movement of waste products and excess fluids from the blood into the dialysis fluid while retaining essential substances like electrolytes and glucose. The aim of using a similar concentration is to prevent the diffusion of these useful substances out of the blood during the treatment, thus ensuring that the patient maintains proper levels of these critical components in their body. This process is crucial in patients with kidney failure, as it helps to manage their body's chemistry effectively.
