SERIM® HiSENSE ULTRA 0.1™ Test Strips provide a quick and convenient means for indicating low levels of total chlorine (chloramine/free chlorine) in feed water used to prepare dialysate. HiSENSE ULTRA 0.1 also provides a convenient means for indicating the concentration of residual chlorine (chlorine bleach) detected in the solution used to rinse dialysate lines following disinfection of hemodialysis
equipment.
Using a 30-second semi-quantitative procedure, the strips will detect total chlorine levels between 0 and 3.0 ppm. The HiSENSE ULTRA 0.1 Test has color blocks at 0, 0.1, 0.5,
and 3.0 ppm; 0.1 ppm is the AAMI (Association for the
Advancement of Medical Instrumentation) maximum allowable
concentration of chloramine in feed water.1
In feed water, a result of 0.1 ppm chloramines or above
indicates that the water should not be used to prepare dialysate because of chloramine breakthrough or exhaustion of the carbon adsorption media in the water purification system. NANT (National Association of Nephrology
Technicians/Technologists) recommends that feed water samples should be obtained after the first carbon tank to monitor chlorine/chloramine levels.2
For rinse water following disinfection of hemodialysis
equipment, a result of 0.5 ppm free chlorine or above
indicates that further rinsing is needed.1

Serim HiSENSE Test Strips give a simple Positive/Negative indication for the presence or absence of total chlorine in treated water used to prepare dialysate concentrates or to reprocess dialyzers. HiSENSE Test Strips have a sensitivity of less than 0.1-ppm total chlorine.
Exposure to chlorine/chloramine in dialysis solution can cause hemolytic anemia in hemodialysis patients.1 Therefore, the dialysis facility must make sure that the level of chlorine/chloramine in final product water used to prepare dialysate or concentrates or for reprocessing dialyzers is below the AAMI Hemodialysis Water Standards of 0.5-ppm chlorine and 0.1-ppm chloramine.2, 3, 4
To make sure that the carbon is removing chlorine/chloramine, use HiSENSE to test a sample of water after the first carbon tank (worker/scrubber tank). A positive test after the first tank indicates this tank should be replaced as soon as possible. If the worker tank yields a positive result for free chlorine or chloramine, another test must be run after the second carbon tank (polisher/finishing tank). If a positive result is obtained after the second tank, the water should not be used to prepare dialysate and both carbon tanks may need to be replaced immediately. If a negative result is obtained after the second tank, the water can be used. However, your water system supplier should replace the first tank as soon as possible.
Prior to starting each shift of dialysis patients, test the water after the first carbon tank for the presence of total chlorine.3

Serim Water Hardness Test Strips give a semi-quantitative indication of the level of hardness in water. Hardness is used to describe the total concentration of calcium and magnesium ions, expressed as ppm (or grains per gallon) of calcium carbonate, CaCO3.
Hard water can adversely affect the dialysis patient as well as damage the water purification equipment. In general, water treatment system manufacturers recommend that the hardness of water entering the RO filter should not exceed 10 ppm of calcium carbonate.1 AAMI Hemodialysis Water Quality Guidelines set the maximum concentration in final product water at 2-ppm for calcium and 4-ppm magnesium.2
Test a sample of water at the post-softener stage of the water treatment process to make sure that the softener is removing calcium and magnesium.
Use daily. Water used in hemodialysis should be monitored closely for hardness.3
Serim Water Hardness Test Strips are supplied in ready-to-use form. When placed in contact with the water sample according to the directions for use, the indicator pad changes color relative to the total level of calcium and magnesium present.
