System Overview 83
CAUTION
Make sure that all sample containers (including tube-cup combinations) are
defined at the System Specification Settings window to avoid probe crashes.
5. Replace the sample tray if it was removed in step
3
and press down on the locking pins
to secure the tray.
6. Replace the sample tray evaporation cover.
CAUTION
Seat the STT cover within the two alignment pins. The dilution probe access
holes must be at the back, and the arrow labels must be aligned next to each
other to avoid probe crashes.
Methods Introduction
Siemens Healthcare Diagnostics provides the procedures necessary for the preparation,
use, and storage of the ADVIA Chemistry reagents in the specific method sheet. Calibrator
information is provided in their respective package inserts.
Sample Collection and Preparation
BIOHAZARD
Any samples of human blood, plasma, serum, urine, or cerebrospinal fluid should
be handled cautiously as a biohazardous material according to good laboratory
practices.
The blood sample should be collected in a commercially available collection tube
using routine venipuncture techniques. A full discussion of sample collection and
preparation is beyond the scope of this document; however this subject is covered
in detail in recent texts by Kaplan and Pesce and Tietz. In addition, the Clinical and
Laboratory Standards Institute (formerly NCCLS) has published two documents on
sample collection.
During sample collection and preparation, avoid hemolysis of erythrocytes. When the
effect of hemolysis on a method is significant, this effect is described in the
Limitations of
the Procedure and Interferences sections of the specific clinical method. Process samples
in a manner that prevents the introduction of clots, fibrin strands, or other solid materials
into the system.
Unless otherwise specified in the clinical method IFU, collect plasma samples using
lithium heparin as an anticoagulant. The individual laboratory should qualify the use of
other anticoagulants.
