What is dialysis water and why it is so important to test?

What is dialysis water?

Dialysis fluids are solutions that are produced by proportional dilution devices incorporated in the dialysis machine (on-line production) or separate from them (off-line production) by mixing concentrated electrolytic solutions or powdered salts with appropriately pre-treated municipal water.

Why Dialysis water testing is important?

A wide variety of chemical and microbial contaminants can be found in municipal water. Dialysis water is used in Hemodialysis which is a medical process wherein dialysis water is transferred in the body of patients who have temporarily or permanently lost kidney function. It maintains the body fluids by regulating the Ph of the patient’s body. Hemodialysis can save the life of a patient but if the treatment water is contaminated, activates monocytes in the patient’s blood stream due to the transit of bacterial products including endotoxins peptidoglycans or its fragments across dialysis membranes can create complications. The water which is used is called dialysate. It is extremely important to assure whether the dialysate is pure or not.

What can be done to prevent malfunctioning of dialysis water?

The best approach in planning a water treatment process is to consider it in terms of quality assurance and continuous quality improvement, which means that it is first necessary to establish the chemical and microbial quality standards to be achieved. The operator should have the knowledge of issues related to the purity of dialysis water.

How is Dialysis water testing done?

First, the water goes through a multimedia filter followed by two carbon tank filters. Now we need to make sure whether the water is soft or not hence it goes through a water softener filter. Last but not the least, it goes through RO system. It is then sent to dialysate prep area where bicarb pH is added. Later it is dispatched to Dialyzer storeroom.
