SERIM GUARDIAN PERACETIC ACID TEST STRIPS
Features	Benefits
Simple "Dip & Read" procedure	Quick and reliable method to determine that the disinfectant remains at or above the minimum effective concentration
Simple to interpret reaction: • Distinct dark brown to blue/black indicator pad is a PASS (PAA concentration >800 ppm) • White indicator pad indicates the disinfectant is a FAIL (PAA concentration <400 ppm)	Can be used with the most common brands of peracetic acid dialyzer disinfectants Accurate and consistent results with less variation between readers
Ready-to-use test	No preparation or mixing of reagents No glass vials or sharps needed No need to dilute samples to test4
Quick, qualitative results in 10 seconds	Allows quick initiation of dialysis procedure
Labeled for dialysis use3	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

WHAT does this product do?
Serim® GUARDIAN™ Peracetic Acid Test Strips indicate the "potency" or concentration of peracetic acid present in peracetic acid/hydrogen peroxide-based disinfectants used to disinfect dialyzers. Dialyzers are generally filled with peracetic acid solutions with a working concentration of 1000 ppm to 1500 ppm.¹

WHY should I use this product?
Inadequate disinfection can result if improper concentration of disinfectant is used. The presence of germicide must be ensured through procedural controls, ideally verified in every dialyzer prior to rinsing.2 Testing for the proper concentration of disinfectant ensures that the disinfectant has been properly diluted and is still present at an adequate concentration.³

WHERE do I use this product?
Test a sample of peracetic acid/hydrogen peroxide disinfectant obtained from the port of the dialyzer.

WHEN do I use this product?
Test each dialyzer prior to use for the presence of disinfectant. Daily verification of the concentration of disinfectant in the batch solution is necessary as are periodic spot-checks of dialyzers.²

HOW to use GUARDIAN Peracetic Acid Test Strips
Serim GUARDIAN Peracetic Acid Test Strips are supplied in ready-to-use form. When placed in contact with the sample according to the directions for use (see below), the indicator pad changes color relative to the concentration of peracetic acid present.

Test Method	Immersion
Sample	Prior to rinsing the dialyzer, collect a sample of disinfectant in the dialyzer port cap or another suitable, clean container sufficient to immerse the indicator pad of the test strip.
Test Strip Technique	Immerse indicator pad into sample for 1 second and interpret results at 10 seconds
Results	PASS – the indicator pad is predominantly or entirely gray/b lue/black or brown FAIL – the indicator pad is predominantly or entirely white
Store bottles of Serim GUARDIAN Peracetic Acid Test Strips at temperatures between 15°- 30°C (59°- 86°F). The lot number and expiration date are printed on the bottom of each bottle.
