Sample Tubes Validated for CTS
Capped tubes can be run directly on the system without removing the cap. The CTS assembly cuts
a small hole in the cap and the sample probe aspirates a sample directly from the tube. With this
procedure, samples are processed faster and more safely.
CTS Validated Sample Tubes
Only validated sample tubes can be run on UniCel DxC Systems with CTS. However, capped and
uncapped tubes can be placed on the same rack. Refer to the table below for validated tubes.
CAUTION
Before placing validated closed tubes on the UniCel DxC Systems, check the top of
the cap for any residual blood. Residual blood can contaminate the sample and
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 contact Beckman Coulter Support Center. Note: Oil on a cap is normal.
Closed Tube Sampling (CTS)
This is an optional feature that allows the system to pierce primary sample tubes. If a CTS assembly
is installed, the operator can enable/disable the CTS assembly. A CTS Tracking database monitors
pierced tubes. If you run a tube again, it will not be pierced again. The sample ID stays in this
database for seven days for a tube that has been pierced.
When a particular Sample ID is manually cleared through Sample Programming, the CTS Tracking
information is also cleared for that Sample ID. If the tube with this particular Sample ID was
previously pierced, reloading this sample tube on any tracking networked instrument will cause it
to be repierced.
NOTE
If a sample ID is cleared at the Host (LIS), the sample ID is NOT cleared in the CTS Tracking database.
•
If a previously pierced sample needs to be rerun, do not clear the Sample ID; use the rerun
procedure.
•
If a Sample ID is manually cleared and reprogrammed for a previously pierced sample, remove
the cap to prevent repiercing.
