Each LOINC item has an associated list of Related Names in its description/details. Some of the Related Names appear to come from the item parts.
But, where do the others in Related Names list come from? E.g. the Related Names for parathyrin are:
Impression/interpretation of study
Point in time
Serum or plasma
For every item, are Related Names stored somewhere? If they are in RELMA.MDB, where? Are some of them dynamically generated? Some, like “Parathyroid hormone” don’t appear to be algorithmically generated.
there are many valuable fields in the LOINC.MDB, and it has changed usages over time. I believe you are referring to RELATEDNAME2 field. RELMA’s development came a while after LOINC began; there could be tables within both that work together in the platform.
Thank you very much, Pam! The RELATEDNAME2 field is exactly what we are looking for.
I previously opened and browsed almost every table but overlooked that field in the big LOINC table. After your helpful reply, I added a public domain Visual Basic script to search the field names in all tables (http://allenbrowne.com/ser-73.html) and located it immediately.
