The usage of the OMx segments in the Master Files MFN and MFR messages is described in Sections 8.3.1, "MFN/MFK - master files notification," and 8.3.3, "MFQ/MFR - master files query," above. Basically the segment groupings described below follow the MFI and MFE segments in those messages (replacing the [Z...] section as follows:
MFN Master File Notification Chapter
MSH Message Header 2
MFI Master File Identification 8
{MFE Master File Entry 8
OM1 General Segment (Fields That Apply 8
to Most Observations)
[other segments(s)]
}
where other segments can be any of the following combinations:
MFI-1-master file identifier code = OMA, for numeric observations
[
[OM2] Numeric Observation Segment
[OM3] Categorical Test/Observation Segment
[OM4] Observations that Require Specimens
]
or
MFI-1-master file identifier code = OMB, for categorical observations
[OM3 Categorical Test/Observation Segment
[{OM4}] Observations that Require Specimens
]
or
MFI-1-master file identifier code = OMC, for observation batteries
[OM5 Observation Batteries
[{OM4}] Observations that Require Specimens
]
or
MFI-1-master file identifier code = OMD, calculated observations
[OM6 Observations Calculated from Other Observations
OM2] Numeric Observation Segment
Note: A test/observation definition may have both an OM2 (numeric) and OM3 (categorical) segment included in case the value may be either numeric and/or categorical. |
