CELL-DYN ® 3200 System Operator's Manual
9140181H—October 2001
The Guide is divided into three parts. The first part discusses the handling and
running of control material. The second part discusses the Westgard
on the CELL-DYN 3200 System and gives guidance for their application in the
hematology laboratory. The third part discusses the X-B Analysis program in
monitoring quality control.
All QC data should be reviewed according to your laboratory's protocol.
The following controls are recommended for use on the CELL-DYN 3200 System:
CELL-DYN 22 (Tri-level), 1 box, 2.5-mL tubes x 12 (List Number 93111-01)
CELL-DYN 26 (Tri-level), 1 box, 3.0-mL tubes x 12, (List Number 01H71-01)
* CELL-DYN controls are packaged in Vacutainer
Controls are used to determine whether an instrument is operating with accuracy
and precision. Controls normally consist of fixed blood cells with assayed ranges
for each measured parameter. Alternately, laboratories may use patient samples
that were previously found to be within set patient limits. CELL-DYN Controls
provide three control levels — low, normal, and high ranges — for each measured
parameter.
All QC data should be reviewed according to your laboratory's protocol. Refer to
the section on Westgard
review protocol. Refer to the section on X-B Analysis for suggestions and
guidelines on interpreting X-B results.
Always mix and handle commercial control materials according to the directions
given in the package insert. Because directions may vary from manufacturer to
manufacturer, pay particular attention to the following:
• Check the condition of incoming control material. Be sure the vials are at the
proper temperature and are not leaking. Check for hemolysis.
• Store controls at recommended temperatures inside the refrigerator,
preferably in a central location away from the door.
• Carefully warm and resuspend the product according to the directions given
in the package insert. Proper mixing is essential for accurate results.
• Check the shelf life and open-vial stability dating. Do not use products longer
than recommended by the manufacturer or the results may be compromised.
• Never subject any vial to excessive heat or agitation.
