Instrument quality control (IQC)
The Roche CARDIAC IQC test serves as a performance check for the optical system of the
cobas h 232 meter. The instrument determines the reflectance value of the signal and displays
“Pass”, “Fail” or the percentage of remission depending on your settings.
“Pass” means that the optical system of the cobas h 232 meter is functioning properly. If “Fail”
appears, the measured reflectance value is outside the confidence interval.
1 Prepare the required IQC test strips
(shown here: Roche CARDIAC IQC high).
2 Make sure that the code chip supplied
with these test strips is also at hand.
