V8 Operator Manual
the V8 has not been able to read the barcode on the sample tube, or there is not a sample tube in every position of a sample rack this
will be left blank.
To avoid disruption to the workflow, the V8 will process all the samples, performing the default assay for any unlabelled or mis-read
tubes. When an unknown tube (missing or misread barcode) is detected, the tube will appear in the missing bar code work list (MWL)
and is identified by .
If all barcodes are read the rack will not appear in this list.
The V8 will check all positions in the rack for samples, and so tubes with unread barcodes will be sampled.
N.B. The barcode must be placed onto the tube between 2cm and 8cm from the bottom of the sample tube.
Adding a tube ID to processed samples
Sample tubes with no barcode or ones that have been mis-read are identifiable in the navigation work list as the tube ID is blank. The
user can enter this information only AFTER the V8 has processed the sample and all the data has been obtained.
To do this, click on the Tube ID column of the unlabelled sample.
This will enable the user to scan the tube with the barcode scanner, or to manually enter a tube ID.
It is also possible to enter sample bar code information from the worklist. To access this, choose
click the toolbar button.
To remove a "Sample Missing Barcode" flag from Platinum
Sample tubes with missing barcodes or mis-read barcodes will be listed in the 'Missing Barcode' list. Before this rack can be used
again on the V8, this list must be manually emptied by the user. The purpose of this list is to ensure the correct assay has been
performed and to notify the system that the user has changed the samples in the rack.
N.B. Removing a rack from the system also removes the sample tube contained within it. As such automated reflex testing cannot be
performed.
How to remove a rack from the worklist
To remove the rack click the Remove Rxx
N.B. Do not click the remove rack button until the data is visible on screen.
Skip position barcode
If you wish to run a rack containing empty sample positions, skip position barcodes should be used. These barcodes are made up of
a series of 6 or 7 zeros (depending if a check digit is used). When the V8 pulls a rack into the sample handling area and this barcode
is detected, the V8 will not sample from this position and this position will not appear in the Platinum worklist.
This is particularly useful when running Immunodisplacement as a default method with unfilled racks to save on unnecessary ID
reagent wastage, when using the gel integration feature of the system with a 9 position IFE gel to save time, or when using the
button and if required any outstanding test.
