Abstract:

The current international standard for dialysis water is ISO 23500-3: 2019, “Preparation and quality management of fluids for hemodialysis and related therapies - Part 3: Water for hemodialysis and related therapies”. In this paper we analyzed and discussed the technical requirements from the aspects of sampling and storage, chemical contaminant limits, microbiological limits, and others, in order to better understand the standard for relevant practitioners.

Key words: Dialysis water, Chemical contaminant, Microbial limit, ISO 23500-3
