Glossary of
terms
The following terms are used in the quality control:
Term Explanation
Accepted result
A measurement value which falls within the statistics
range.
Control range
The range within which a measurement should fall.
Typically the control range is set to be the mean
±
2 SD
(see
Quality control setup
in
chapter 3
). This range can be
set using the lot-to-date range (2 SD) calculated by the
analyzer, or it may be user-defined.
Insert limits
Upper and lower control limits, established by Radiometer,
printed in the insert provided with each box of control
solutions.
Lot-to-date range
A range calculated by the analyzer from measurements
taken on a lot of a particular control solution. It is
represented by mean
±
2 SD.
Measuring range
The range for each parameter the analyzer is capable of
measuring. Refer to
Measured parameters
in
chapter 13
for the analyzer measuring range for each parameter.
Statistics factor
The factor by which the control range is expanded
(multiplied by) to determine the statistics range. The
recommended statistics factor is 1.5.
Statistics range
The range within which a measurement must fall in order
to be included in the quality control statistics. It is
determined by multiplying the control range limits by the
entered statistics factor. It is typical that the statistics
range is set to the mean
±
3 SD.
For detailed information on terminology and principles for the quality control
systems, please refer to the
Quality Control Systems Reference Manual.
NOTICE:
In cases where the first blood sample measurement after a measurement on a
QUA/5+ or Aut/5+/6+ control solution is to be performed
with HbF correction (either set up for all levels or for
F
HbF> 20 %), a rinse must
be called prior to the blood measurement to ensure accurate oximetry results.
