Serim Residual Chlorine Test Strips give a semi-quantitative indication that chlorine bleach has been adequately rinsed from the hemodialysis machine, bicarb jugs, bicarb mixing tanks or water delivery systems following disinfection.
If the hemodialysis machines are disinfected with bleach, it is important to ensure that the disinfectant has been properly rinsed and residual chlorine concentrations are below concentrations which may potentially cause adverse patient events, such as allergic reactions, hemolysis and death.1,2
AAMI Hemodialysis Water Quality Guidelines set the maximum allowable concentration of free chlorine at 0.5-ppm, therefore the concentration of residual concentrations of bleach must be below 0.5-ppm prior to initiating dialysis.1, 2, 3, 4
Use Serim Residual Chlorine Test Strips to test rinse solution from the drain line of the hemodialysis machine or appropriate sampling points of the bicarb mixing tanks or jugs and water systems.
Use Serim Residual Chlorine Test Strips after rinsing the bleach from the hemodialysis system and prior to initiating dialysis.
Serim Residual Chlorine Test Strips are supplied in ready-to-use form. The strips can be used as a quick, qualitative screening test; detecting concentrations of bleach above or below the 0.5-ppm AAMI action level. The strips can also be used as a semi-quantitative method to estimate chlorine concentrations between 0 and 5-ppm. When placed in contact with the sample according to the directions for use, the indicator pad changes color relative to the concentration of chlorine.

Serim Residual Peroxide Test Strips give a semi-quantitative indication that the peracetic acid/peroxide disinfectant concentration has been reduced to safe levels after rinsing the dialyzer, dialysis machine or water distribution system.
Disinfectants must be rinsed from the dialyzer to below known toxic levels within a rinse-out period established for the particular germicide. Residual disinfectant should be measured by a test of appropriate sensitivity according to a written procedure to ensure that the disinfectant level is below the recommended maximum residual concentration. Inadequately rinsed dialyzers can lead to acute reactions in the dialysis patient3, 4, 5
The peracetic acid/peroxide disinfectant concentration must be below 3-ppm prior to initiating dialysis.1,2,4 Peracetic acid disinfectants contain peracetic acid, hydrogen peroxide and acetic acid. The industry standard for the residual concentration of peracetic/ peroxide disinfectants is set at 3-ppm. Because peroxide is present at a higher concentration than peracetic acid in diluted solutions, the 3-ppm target level is actually based on the peroxide concentration. Therefore, when peroxide is less than 3-ppm, peracetic acid levels will be even lower.
Use Serim Residual Peroxide Test Strips to test rinse solution from any convenient port where the solution has passed through the dialyzer. If a peracetic acid/peroxide disinfectant was used to disinfect the water system or dialysis machines, obtain a sample of rinse solution from any convenient port in the rinse line per manufacturer's instructions.
Use Serim Residual Peroxide Test Strips after completing the dialyzer rinse procedure and prior to initiating dialysis. AAMI Standards state that residual chemical disinfectant should be tested according to manufacturer's instructions.
Serim Residual Peroxide Test Strips are supplied in ready-to-use form. When placed in contact with the sample according to the directions for use, the indicator pad changes color relative to the concentration of peracetic acid/peroxide disinfectant present.
