# Terminology Data - Logical Observation Identifiers Names and Codes (LOINC)

## Supported recent Version

2.81

## Description

LOINC, which stands for Logical Observation Identifiers Names and Codes, was initiated in 1994 by Clem McDonald, then an investigator at Regenstrief Institute, a non-profit medical research organization associated with Indiana University. Indianapolis-based Regenstrief organized the LOINC Committee to develop a common terminology for laboratory and clinical observations because there was a growing trend to send clinical data electronically from laboratories and other data producers to hospitals, physician's offices, and payers who use the data for clinical care and management purposes. 

There are two packages: 
1. The ART-DECOR Release 3 Terminology Package in CADTS Format
1. For the sunset phase there is also an ART-DECOR Release 2 Terminology Package called classic format
