Automatic QC
The solution pack contains three levels of QC solution. The analyzer is designed
to run each level once every 24 hours. However, it is possible to set up a
schedule to run QC more often, if required, as described in section QC Schedule
in chapter 1.
The QC solutions that come from pouches in the solution pack enter the sample
path through the inlet as a normal blood sample. The only difference is the
position of the inlet that remains in the closed position.
Stage Description
1. When an automatic QC is scheduled to be run, it will postpone
measurements etc., unless the analyzer is busy measuring a blood
sample. In this case, the scheduled QC will be run after the analyzer
has completed the measurement.
2. The QC measuring procedure begins:
 For QC level B only: A measurement of high oxygen is performed
on a gas from a pouch that is aspirated before the QC solution.
 Measurement of the QC solution is performed as soon as it is
positioned in the measuring chambers.
3. The result is saved in the Quality Control log.
4. The result is compared with the defined control range, measuring
range and statistics range.
5. The absence of any markings next to a parameter indicates that a
parameter was measured without any fault.
Marking Explanation
? Error in the previous calibration, or analyzer
malfunction.
W
A violated Westgard Rule.
R
A violated RiLiBÄK rule.
Parameter value is outside the control range, but
inside the statistics range.
Only the values within the statistics range are
considered accepted and are included in the QC
statistics.
Parameter value is outside the statistics range and
is not included in the statistics.
Parameter value is outside the range of indication.
Measurement is not included in the statistics.
*
Parameter values with user-defined corrections –
see section Parameters and input setup, chapter 1
for details
….. Parameter value could not be calculated, most likely
due to a system error or malfunction. These values
will for the most part be accompanied by a "?". To

6. After the measurement is complete, it is followed by a rinse. For
further information on the rinse process see page 3-6.
