Abstract
Observed data of endotoxin, in dialysate, usually decrease with passage of time, especially after freezing. Therefore, a 50μl of human serum albumin with 0.02% aqueous solution for 2ml of dialysate was used to obtain the stable data. The endotoxin activity in dialysate during dialysis treatment is decreased within the first 60 min. and reaches minimum level. The results obtained front a few dialysis centers, show that the main contaminated position of dialysate, at a well-maintained dialysis center, is the RO tank.
