Dialysing unit (artificial kidney) contains a fluid which is almost same as plasma except that it has
1. high glucose
2. high urea
3. no urea
4. high uric acid
In a dialyzing unit (artificial kidney), the dialysis fluid (dialysate) is designed to have a composition almost like normal plasma but without urea or other waste products. This concentration difference allows urea and other toxins to diffuse out of the patient's blood into the dialysate, cleansing the blood.
It does not contain high glucose, high urea, or high uric acid.
Instead, it usually has normal levels of salts and glucose to maintain balance but no urea so that urea can move from blood to dialysate by diffusion.
