Chapter 3: Barcode Reader Option 43
Barcode Symbologies
Although data entry using barcodes is generally more reliable than manual data
entry, it is not guaranteed to be 100% accurate. To increase accuracy, use of
barcode symbology checksums is recommended.
1D Barcode Symbologies
BD Biosciences has evaluated the following 1D barcode symbologies for use with
the BD FACSCanto II flow cytometer, and has these recommendations:
Using barcode symbologies with checksums disabled increases the
likelihood of incorrect information transfer, including sample ID
assignments. This can result in a mismatch of sample IDs and sample
results.
By default, the barcode reader has checksums enabled. We recommend you
do not disable checksums, or use barcode symbologies without checksums.
Barcode Symbology Recommendation
Code 128 Preferred.
Code 39 Acceptable if barcode labels are printed with the checksum
digit. By default, the barcode reader recognizes the checksum
digit when reading the Code 39 symbology. However, if labels
are printed without a checksum digit, contact your BD service
representative for instructions on disabling the checksum
feature.
Codabar The barcode reader does not support the checksum feature
when reading the Codabar symbology.
