SECTION 3
OPERATING THE CHLOROCHEK
3.6 Quality Control
To ensure adequate quality control, Sweat Control Solution (SS-150) should be run at all three levels and the 100
mmol/L NaCl/H
O Standard Solution (SS-251) should be assayed before running any patient samples. This must be
2
done at least once a day and after conditioning with a freshly prepared Working Solution.
The control frequency should be adapted to Quality Control procedures of each laboratory and any regulatory
requirements. Results should be within the defined ranges.
If values fall outside of the defined ranges, then clean the measurement electrodes (see Section 4.2) or check the
accuracy of the pipette (see Section 4.1). Quality control materials should be used in accordance with local, state,
and/or federal guidelines.
NOTE:
Over time and use the anode (red housing) silver electrode will be used up as it precipitates with the chloride
ions. This electrode will have to be replaced periodically as it gets smaller. As long as the ChloroChek passes
quality control the anode is still usable for sample measurement.
