Part Search

This section last updated: 2022-07-26 (2 years ago)

The fully-specified name of LOINC is divided into six main Parts, as described in the LOINC Users' Guide. The Part Search screen within SearchLOINC and RELMA lets you search for matching LOINC Parts.

Part Search results include the Part number, the Part type (Component, Method, etc.), the Part name/concept, the Part display name (an expanded version of the name/concept), and the preferred abbreviation for that Part.

The search string must follow the syntax described in the Syntax section of this document. The field names listed in the Part Field Names section of this document can also be used in the search string.

The Reference Information button, when checked, enforces that search results must contain a reference information Description.

Additional description and discussion of LOINC Parts is provided in the LOINC Users' Guide.
