LOINC Table, Reports, and Users’ Guide

The LOINC table includes fields for the LOINC codes and each of the six parts of the fully-specified name. There are many other fields (described in the Users' Guide) that contain synonyms, comments, and other information. The LOINC table is available in several file formats.

The LOINC distribution also includes several LOINC Accessory Files and other documentation.

An export of all of the LOINC terms that are in the complete table with a subset of the fields that are both crucial for defining each LOINC term and whose structure is anticipated to be stable over the long-run. We are providing this format in order to make it easier for implementers to update to the latest LOINC release without having to make changes to their database structure. The map_to.csv file is included in the Core table download so that users can update their mappings for deprecated terms without having to download a separate artifact. However, depending on their use case, some implementers may still need to refer to the complete LOINC table in order to find all of the relevant information. This zip file archive contains: 1) the LOINC Core table in CSV text format; 2) the LOINC map_to table in CSV text format; 3) Loinc Table Core Release notes in a text file format; 4) Loinc Table Core Readme in a text file format; and 5) the LOINC License in a text file format.

LOINC Table Changes File

Contains all records that have been edited since the last release, including changes in many ancillary attributes such as RELATEDNAMES2, SHORTNAME, and COMMENT fields. We make lots of edits to such fields, so most of these changes do not alter the LOINC term name. This file is in a Microsoft Access™ database format, compressed as a zip file.

LOINC Table Changes Report

A report that highlights all the changes to the primary LOINC name fields since the last release. LOINC follows good terminology management practices, so these changes reflect modifications to our naming convention rules, style, and efforts for consistency rather that changes to the concept meaning.
