Dialysis Clinic Water Sample Process

Posted by 10 Feb, 2011

If you are setting up a new dialysis clinic, or just revising internal guidelines, this may help you to understand the full process, and become more familiar with water treatment in the dialysis clinic.

If you are setting up a new dialysis clinic, or just revising internal guidelines, this may help you to understand the full process, and become more familiar with water treatment in the dialysis clinic.

Check the incoming water source

Your clinic’s water source should be tested periodically to make sure that the level of chemical contamination meets AAMI (Association for the Advancement of Medical Instrumentation) standards. Send a sample of your water to a qualified lab that can analyze the samples according to AAMI standards. Since dialysis clinics are required to meet AAMI standards at all times, you should check the water about every quarter to ensure that you are meeting AAMI standards. Samples for product water chemical analysis should be drawn from a sample port immediately after the RO or DI system. You can then determine if your water filtration system is degrading, or if there are changes to the incoming source based on past analysis trends.

When and Where to Test the Water:

When collecting samples from your water treatment system, be sure to  run the water from sample ports for at least one minute at normal pressure and flow rate before collecting the water sample. Do not disinfect the sample port – this could lead to false readings. If you must disinfect, use alcohol instead of bleach, and only take a sample once the alcohol has completely dried. Use a reliable, accurate, and simple instrument to measure samples. If you do not already have an instrument, you can find some here that are designed specifically for dialysis clinics:

Proper Testing Protocol

To properly test the system, take samples from the product water distribution pipes at the following locations:

dialysis water quality room

Site 1:  Take a sample at the point where the water leaves the RO machine, before it enters the holding tank (Indirect System), or before it goes to the treatment room to provide water for dialysis machines (Direct System).

Site 2:  If an RO water holding tank is present, take the sample at the point where the water leaves the tank.

Site 3: Take one at the end of the return line of the RO water distribution loop, whether it is returning to the RO or a water holding tank. If a bacteria filter is installed anywhere in the system, take samples from sample ports both pre and post filter.

Site 4: Take one at the point where water enters into the dialyzer reprocessing system, whether it is a manual or automated system. (Note: If a sample port is not present, install one.)

Site 5: Take one at a point where water enters equipment used to prepare bicarbonate and acid  concentrate. (Note: If a sample port is not present one should be installed.)

Site 6: Take another at the point where the dialysis machine is hooked up to the product water loop. If a dialysis machine is consistently attached to that location, you may culture the machine instead of the water outlet.

Site 7: If your facility uses softened,  dechlorinated water as a backup source, you must perform cultures and a Limulus Amebocyte Lysate (LAL) test on this water,  because the RO is the primary source of bacterial protection for the patients.

The need for proper dialysis water quality tests

Kidney failure is a big problem in the U.S. and it is only growing. More than 350,000 Americans receive dialysis treatment through private clinics, independent centers, and hospitals, while 8% of U.S. dialysis patients treat themselves at home.

As more and more Americans develop a need for dialysis treatment, water quality instrumentation manufacturers are looking for a way to help clinics improve their quality standards and efficiency.

Part of the problem

If you are constantly recalibrating your instruments, performing a decontamination process, or sending the meter in for repair, then you’re wasting time. As the number of dialysis patients increases, delays in the water quality testing add up. Today, you have options when it comes to testing dialysis water quality and dialysate composition.

Some instruments require annual calibration or an inconvenient decontamination process after each use. Using an instrument that requires direct contact with fluid means you have to decontaminate the meter before helping the next patient. If done incorrectly, the water treatment system and distribution piping can become contaminated, putting lives at risk.

More downtime occurs when dialysis meters have to be sent back to the manufacturer for annual calibration. If you are a clinician or biomedical equipment technician at a dialysis clinic, then you know how frustrating it is to work with problem instruments.

Make your job easier with the Digital Dialysate Meter™ D-6

MyronLMeters.com features the new Myron L Digital Dialysate Meter™ D-6.

Digital Dialysate Meter D-6

Unlike other instruments, this meter does NOT have issues with holding calibration or giving consistently accurate readings. It does NOT have an inconvenient decontamination process or require any annual factory calibration. The meter does NOT use paper strips or reagents that expire or allow for subjective interpretation of results.

The D-6 simplifies testing in a variety of clinical applications: dialysate testing, water quality control, system disinfection, equipment calibration and effluent monitoring.

The D-6 tests both acetate and bicarbonate dialysate quality. It measures conductivity, pH and temperature to ensure proper mixing during dialysate preparation and as a final check of dialysate quality before hemodialysis treatment.

Order a bluDock™ Bluetooth Wireless Communication Package and your meter can communicate wirelessly with your computer to download your saved measurements. Say goodbye to clipboards, data entry, and human error.

Make your job easier now, order online and SAVE 10%.
