Protocol 000004 – blood component dispatch acknowledgement - Standards for electronic data interchange within the UK Blood Transfusion Services - Chapter 25

Two data line structures are defined within this protocol:

1. A single line containing administrative information (see Table 25.12).
2. A multiple occurrence line with an entry for each item on the dispatch (see Table 25.13).

To distinguish between the two line types, a line type indicator is included as the first field in each line following the line number.

Please see explanatory notes below each table.
