SERIM GUARDIAN HiSENSE TEST KIT
Features	Benefits
Simple to interpret reaction; • Blue spot is a positive • No blue spot is negative	Accurate and consistent results minimizes variation between readers Eliminates difficult-to-read color wheels
Detects water samples containing 0.1 ppm total chlorine	Complete confidence that chlorine breakthrough will be detected when 0.1-ppm limit is reached
Proven reliability, stable performance	Confidence in test results throughout the product's shelf life
Product performance is not affected by high levels of common water constituents	Minimize concerns that performance may be affected by quality of incoming water Consistent results with most types of water sources
Ready-to-use strips	No preparation or mixing of reagents No calibration or instruments needed No glass vials or sharps needed
Simple procedure with only 3 steps	No calculations needed
Labeled for dialysis use4	No need to qualify an "off-label" test for dialysis use No need to monitor changes in product performance from lot-to-lot
Each bottle clearly labeled with: • Lot number • Expiration date	Traceability of product from manufacturing to final user Leaves no doubt as to the age or integrity of the product
Convenient packaging	No waste of strips, even for low volume testers

WHAT does this product do?
Serim® GUARDIAN™ HiSENSE Test Strips give a simple Positive/Negative indication for the presence or absence of total chlorine in treated water used to prepare dialysate. Serim Guardian HiSENSE Test Strips have a sensitivity of less than 0.1ppm total chlorine.

WHY should I use this product?
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 is below the AAMI Standards of 0.5 ppm chlorine and 0.1 ppm chloramine (or 0.1 ppm total chlorine).²

WHERE do I use this product?
Collect a sample of water after the first carbon tank^{2, 3, 4} and test it according to the HiSENSE directions. If the results are positive, a second sample should be taken immediately after the water leaves the second tank. If there is chlorine leaving the second tank, dialysis should be discontinued in the facility. If there is no breakthrough after the second tank, the water can be used but the chlorine level should continue to be monitored after the second tank on an hourly basis until the primary tank is replaced.

WHEN do I use this product?
Prior to starting each shift of dialysis patients, test the water after the first carbon tank for the presence of total chlorine3. It is very important that the water system be in full operation for at least 15 to 20 minutes before you take your first test.

Test Strip Technique	Place a Serim GUARDIAN HiSENSE Test Strip in the strip holder (concentrator).
Sample	Fill the reservoir in the Strip Holder using a sample of water collected after the first carbon tank. Add 1 drop of HiSENSE Reagent Solution. Allow the water sample to drain from the reservoir (~7 minutes), remove the strip from the holder & interpret the results.
Results	POSITIVE for Total Chlorine - The circular Reaction Zone on the HiSENSE indicator paper flap will display a blue spot indicating that the concentration of total chlorine is at or above 0.1 ppm and should not be used. NEGATIVE for Total Chlorine - The circular Reaction Zone of the HiSENSE Test Strip will be no darker than the surrounding indicator paper indicating that the concentration of total chlorine in the water tested is less than 0.1 ppm.
Store bottles of Serim GUARDIAN HiSENSE Test Strips at temperatures between 15°- 30°C (59°- 86°F). The lot number and unopened expiration date are printed on the bottom of the bottle. Serim GUARDIAN HiSENSE Test Strips have a 3-month opened use-life.
