ISBT 128 Concatenation

In 1994 the International Society of Blood Transfusion (ISBT) ratified a standard

for communicating critical blood information in a uniform manner. The use of ISBT

formats requires a paid license. The ISBT 128 Application Specification describes

1) the critical data elements for labeling blood products, 2) the current recommen-

dation to use Code 128 due to its high degree of security and its space-efficient

design, 3) a variation of Code 128 that supports concatenation of neighboring

symbols, and 4) the standard layout for bar codes on a blood product label. Use the

bar codes below to turn concatenation on or off. Default =Off.
