New ISO Water Quality Standard for Hemodialysis Brochure

The recent adoption of higher standards by AAMI means the quality of water used in dialysis treatment will increase. The new standard has 2 important aspects to it. First, acceptable microbiological levels have been reduced by more than 50%, as noted in the chart below. Second, the testing protocol used to determine bacteria levels is a much more sensitive cultivation technique yet includes a deviation to allow for other test methods. The net result is that existing water system designs may or may not consistently produce water that meets the new standards.
