 ok, then that's fine - a modification to the database is required,
either adding a table linking lab_request to test_result (it's not
many-to-many it's one-to-many so this is excessive but if you decide
to do it i'll go with it) or adding fk_lab_request to test_result
(which is one-to-many and more like what's actual reality).

 remember karsten that OBXs *do not* have *any* information which
allows them to be cross-referenced to anything: they exist solely
under their OBR-ORC.  there are no fields in an OBX line telling you
what they refer to.  the information is contained in their parent
OBR-ORC record.
