We don't need them *in their own table structure* however the the

be renamed note_test_org)
From reading a bunch of stuff (the HL7 standard itself is not freely
available) on the web (such as http://aurora.regenstrief.org/
~gunther/)
I figure that HL7 wants OBR to be what we consider lab_request to be.
I think in the first iteration we will equate the two and add fields
as necessary. IOW
If we had a field of same or equivalent name in lab_requests, the OBR
024 "Diagnostic Service Section" names could update/append into here.
we will add a field lab_request.service_section.
I agree that the service_section has (only) *limited* value. The
section info is not *totally* valueless, it serves mainly if there is
an issue with your test of interest, and you end up needing to know
what section technician you will need to speak with, because the
front desk never knows when the infrequently-performed test that you
are waiting for will be done, nor do they tend to know --- when there
is a suspicious or unclear result --- the section to which they
should forward your call, and you can burn up a lot of the time on
the phone waiting.
If we reconsider, and suppose that we ordered tests whose information
returned by the lab included (any of which could be resulted or pending)
OBR 004 Universal Service ID = YGT^Gamma GT
OBR 024 Diagnostic Service Section = CHEM4
OBR 004 Universal Service ID = ALT^ALT
OBR 024 Diagnostic Service Section = CHEM4
OBR 004 Universal Service ID = AST^AST
OBR 024 Diagnostic Service Section = CHEM4
OBR 004 Universal Service ID = HP^Hematology Panel
OBR 024 Diagnostic Service Section = HAEM1
OBR 004 Universal Service ID = PT^INR
OBR 024 Diagnostic Service Section = HAEM3
OBR 004 Universal Service ID = URC^URINE CULTURE
OBR 024 Diagnostic Service Section = MICRO3
OBR 025 Result Status = P (pending)
OBR 004 Universal Service ID = ENDO^Endometrium Culture
OBR 024 Diagnostic Service Section = MICRO3
OBR 025 Result Status = P (pending)
If we ask ourselves
"What would be most useful to capture from the above, and keep with
the lab request as note_org_info *instead* of as service_section ... "
I would venture it could be:
Gamma GT, ALT, AST, Hematology Panel, URINE CULTURE (P), Endometrium
Culture (P)
IOW subsegments that combine the test names with their status (when
not FInal).
