Rapidlab 1265 System Performance Characteristics
All performance data presented in this section was generated using the
Rapidlab 1265 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 1265 system.
Precision on Controls
Quality control materials, including manual (QC) and automatic (AutomaticQC)
were analyzed on the Rapidlab 1265 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 1265 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 1265 systems over a minimum of
10 days. AutomaticQC is automatically scheduled to run (single sample)
independently 3 times per day. The following tables summarize the results of the
Rapidlab 1265 system precision for manual QC and AutomaticQC.
