Safety Notice
Summary of Precautions
Quality Control
Laboratory Quality Control practices should be commensurate with laboratory operations. Refer to
assay Instructions for Use and CLIA '88 (update 1/24/2004 Section 493.1256).
Racks Replacement Precautions
Racks should be replaced every five years. Damaged racks should not be used on the system or in
the SPINCHRON Centrifuge.
Ratio Pump Quad-Ring Replacement Precautions
Be careful not to twist quad-rings or O-rings during installation, as this could result in reagent
leakage or ratio pump failure.
Reagent Volume Precautions
Check reagent volumes before you start a run. Failure to operate with sufficient reagent causes
erroneous chemistry results. In some cases, results are obtained without proper amounts of
reagents in the modules. Therefore, before you start a run, make sure that sufficient reagent is
available to complete the run.
Modular chemistry reagent containers should not be handled while the system is performing
modular chemistry measurements.
The use of expired reagents may cause erroneous results.
Residual Blood Contamination Precautions
Before you place your validated closed tubes on the DxC System, check the top of the cap for any
residual blood. Residual blood contamination into the sample could affect results. If blood is
present, remove it by using a cotton-tipped applicator stick moistened with DI water. When running
in the CTS mode, if tubes off-loaded from the UniCel DxC Systems have water or droplets of water
on the caps, disable the CTS and the contact the Beckman Coulter Support Center.
NOTE
Oil on a cap is normal.
Reuse of Sample ID Precautions
If your LIS or normal workflow requires the reuse of sample IDs, the sample programming should
be cleared from the DxC at a time interval that is less than the shortest time of sample ID reuse.
Failure to observe this warning causes new requests to be merged with tests from incomplete
samples that previously used that ID.
