9-38 Regulatory Information
10. Aspirate the sample.
a. Position tube so that the sample probe is immersed into the well-mixed
sample. The sample probe should not contact test tube surface, which
could block the free flow of sample into the probe.
b. Press the aspirate plate. The sampling light flashes during aspiration.
Complete sample aspiration takes approximately 6 seconds and will
consume almost the entire prepared sample. Do not remove sample
until sampling light has stopped flashing. There is no Probe Clog
message to indicate incomplete sample aspiration in the CSF mode.
Carefully observe the sample during aspiration to ensure that the
sample probe is below the surface of the sample during the entire
aspiration.
c. When the sampling light stops flashing, remove the tube.
11. When the analysis of
all
CSF samples is complete and you would like to
return to whole-blood operation, select
Exit
. The system automatically
returns to the Whole Blood Manual Sample ID window.
When you exit CSF operation after running at least one sample or any cycle,
the system asks if you are sure you want to exit. Select
OK
to leave the
Cerebrospinal Fluid (CSF) window. Select
Cancel
to keep using the CSF
features.
NOTE:
If any samples were processed or cycles run in the CSF mode, the
system will perform a hydraulic exit cycle. If no samples or cycles were run
in CSF mode, the system simply exits CSF mode.
Tip
If a system left in CSF mode has made the transition to Standby and you want to
exit CSF mode to run whole-blood samples, switch to whole-blood operation
before
exiting standby. This will reduce unnecessary reagent use.
Quality Control
Quality control of the CSF Assay is performed using ADVIA 120 TESTpoint
CSF Controls containing one each of Level 1 and Level 2 controls. These
controls are intended to be integrated into a clinical laboratory’s own quality
control program and procedures. Follow the package insert instructions for
assaying the control products.
