Bar codes in laboratories are an essential component to an automatic identification system that allows patient data to be captured.
Layusa said the
bar codes would replace the old system, where examinees' name cards were inserted in exam sheets to properly tag their booklets.
The foremost was to turn the label stock by 90[degrees] in the printing systems so that any white streaks that might be caused by a defective print head would be perpendicular to rather than parallel with the bars in the
bar code. Thus, even ifa
bar code had a white streak transversing the code, there would be sufficient high-quality bars above or below the streak so that most
bar code readers would give a correct read.
On this note, the benefits of device-specific
bar codes in conjunction with a single, central database to be used for cross reference, all culminate in improved patient safety.
Laboratory professionals know patients through the
bar code received with a requisition and through specimens delivered to the lab.
The
bar code system also eliminates errors such as late payment notices to customers who have already put a cheque in the mail.
In hospital pharmacies, for example, many medications still arrive without a
bar code, and repackaging and labeling is a large-scale undertaking.
The International Air Transport Association (IATA) has revealed a global standard to pave the way for global mobile phone check-in through the use of two-dimensional (2D)
bar codes.
Enhanced
bar code scanner: Accu-Sort Systems, manufacturer of the Axiom-XT
bar code scanner, has introduced a version that can read high-density
bar codes, as well as potentially reduce the number of no reads.
