Learning About the System
Parameter Description
expected (target)
range
for each parameter, the measurement limits above and below
the mean where the majority of the QC samples are expected
to fall
action range for each parameter, the measurement limits above and below
the mean requiring immediate action
sample results the results for each parameter, the QC sequence number, and
the analysis date and time
cumulative statistics
for each parameter, the mean, standard deviation, coefficient of
variation, and number of samples analyzed
Bayer Diagnostics Service Representatives use File 13 to store data during service
calls. File 14 is the discard file. The system stores QC results in File 14 that you
discard at the end of QC analysis. You can move and change the status of a file in
File 14 using Recall. Refer to Recalling QC Data in Section 2.
The system assigns a sequence number to each QC sample in the order that you
analyze the samples. QC sequence numbers are independent of the QC file
information. Sequence numbers run from 100 through 99999 and then repeat.
Identifying QC Files Automatically
If the auto ID option is on, the 800 system automatically identifies the QC sample
results and selects the appropriate QC file to store the results. The system
compares the results for pH and pCO
2
to the target ranges defined for each
parameter. If the results for these parameters are within the target ranges, the 800
system selects the QC file in which to store the results and prompts you to confirm
the file assignment. If the results are not within the action range, or if one or both
of the pH or pCO
2
sensors are not calibrated or are not available, the system does
not select a QC file. You can then select a QC file for the results. Refer to Selecting
Automatic QC File Assignment in Section 5 to use this option.
Accepting QC Results Automatically
If the 800 system is connected to an LIS or a data management system, you can
use Auto Accept to have the system automatically accept QC results and send them
to the LIS or data management system. You can then accept, reject, or discard
results at the LIS or data management system. Refer to Selecting Automatic
Acceptance of QC Results in Section 5 to use this option.
