The UDI for a given manufacturer's product/model/package will be issued and registered by a small number of non-profit agencies such as GS1 and HIBCC
. In the case of GS1, this will be based on the GS1 Global Trade Identification Number (GTIN), which can be thought of as a grown-up version of the UPC codes that can be seen at the supermarket.
Of the 30 existing bar code symbologies, the ones used most widely in the laboratory--approved by the Health Industry Business Communications Council (HIBCC
)--are Codabar, Interleaved 2 of 5 (I 2 of 5), Code 39, and Code 128.
Comprising 70 fields, each label consists of many type fonts and sizes, graphics, boxes, reverse type, two logos, and an HIBCC
(industry standard) bar code.
For many products that require direct part marking, the type of product identifier best suited for compliance with new FDA regulations is a GS1 or HIBCC
DataMatrix barcode, a two-dimensional barcode capable of holding large amounts of data in a relatively small space.
The Health Industry Business Communications Council (HIBCC
) has specified the use of code 3 of 9 or code 39 for health industry applications.
