Rapidlab 1200 Operator's Guide: System Specifications
NOTE:
interference to subsequent measurements of other samples on the calcium sensor.
There is no impact to sensor calibration or sensitivity, and other samples that are
run immediately after the Irenat patient sample can be run without impact.
Ethylene Glycol Interference when Measuring Lactate
and Glucose
Falsely elevated lactate results may be reported as a result of non-specificity of the
lactate oxidase enzyme towards ethylene glycol metabolites. Falsely decreased
glucose results may also be reported.
Performance Characteristics
This section contains performance characteristics for each Rapidlab 1200 system
in the series. Each system contains performance data within the following criteria:
•
precision on Controls
•
recovery and Precision Values–as appropriate to the system
•
method Comparison with Human Whole Blood Samples
Rapidlab 1240 System Performance Characteristics
All performance data presented in this section was generated using the
Rapidlab 1240 system. The system performed calibrations using the default
settings recommended by Siemens for optimum performance. All reported values
were corrected to 760 mmHg. All data was collected at room temperature (about
23°C). You should determine your own performance characteristics in your
laboratory with your Rapidlab 1240 system.
Precision on Controls
Quality control materials, including manual (QC) and automatic (AutomaticQC)
were analyzed on the Rapidlab 1240 system. Manual QC is performed by the
operator while AutomaticQC is performed automatically by the system based on
the QC frequency defined in the system software. The results are presented here.
Precision on manual aqueous quality control materials was estimated using a
minimum of 3 Rapidlab 1240 systems. Controls were measured over a minimum
of 10 days.
Precision on the aqueous quality control materials in the AutomaticQC module
was estimated using a minimum of 3 Rapidlab 1240 systems over a minimum of
10 days. AutomaticQC is automatically scheduled to run (single sample)
independently 3 times per day.
