Hi, first of all, I am no med student or has anything solid background in the medical field, in fact, I am an App Developer, I have a project that uses LOINC Codes (I have no documentation from the previous developer of this project), but for some reason, I need to know whether the procedure is a pathology, profile, room and sample temperature. I’ve searched on RELMA & Loinc Database for every Loinc Code I have on my example to identify these fields and I am lost with lots of terminologies. Does anyone know where to point me or explain which field to look at when determining these data/fields? Here is my example LOINC Codes: 13457-7 10331-7 19769-9   I know for a fact that the 19769-9 is an Anatomic Pathology, due to its being given, from that I am now lost.   ---

Hi Bien, You might be interested in the CLASS field of each LOINC; here is the legend to those abbreviations: [https://loinc.org/kb/users-guide/classes/](https://loinc.org/kb/users-guide/classes/) Also, there are attempts to create an ontology of the terms. You can read about it in the User’s Guide [https://loinc.org/kb/users-guide/document-ontology/](https://loinc.org/kb/users-guide/document-ontology/) or under Relma you can visualize the hierachy by clicking on the Hierarchy & Search Limit tab, then clicking on one of the specific Hierarchy tabs. Trying pasting in 19769-9 in each of the tabs to see what resonates for your project/application. All the best, Pam ---
