2.25.5 Master file update examples: with original and enhanced acknowledgment protocol

This example shows the lab system using the Master Files specification to send two update test dictionary entries to an ICU system. The OM1 (observation dictionary) segment, currently under development by HL7 and ASTM, carries the dictionary information. Several varieties of acknowledgment are shown. The choice of acknowledgment mode is site-specific.

2.25.5.1 Original mode example:

MSH|^~\&|LABxxx|ClinLAB|ICU||19910918060544||MFN^M03|MSGID002|P|2.2

Original mode acknowledgment of the HL7 message according to MFI Response Level Code of AL.

2.25.5.3 Delayed application acknowledgment

Note: If the MFN message in Section 2.25.5.1, "Original mode example," had not required an application acknowledgment at the message level (i.e., the application acknowledgment code of the MSH segment = NE), the (Master Files Chapter defined) MFD message could be used to provide a delayed application level acknowledgment not tied to the original MFN message.

The following example includes an acknowledgment for an MFE segment not in the original message. This additional MFE was sent via another MFN message.
