OMB: Blood product order message

This page lists the structures and trigger events OMB defines, taken from the standard. The written commentary that theADT page carries has not been written for OMB.

Recognising OMB messages

OMB announces itself in MSH-9 like this:

MSH-9OMB^O27^OMB_O27
  1. MSH-9.1OMBmessage code: what kind of message this is
  2. MSH-9.2O27trigger event: what happened in the real world: blood product order message
  3. MSH-9.3OMB_O27message structure: which segments to expect, and in what order

How to use these specifications explains MSH-9 in full, with a worked example.
