Getting Started with LOINC

Jumpstart your path to LOINCing prowess.


Getting LOINC

Updated versions of LOINC (and the RELMA desktop mapping program we'll describe next) are distributed twice per year; in June and December. You can download LOINC right from this website.

In the interim between public releases, we pre-release new codes requested by users and under development by the LOINC team. That way you can get a heads-up on what's coming. You can view these "in-process" codes here.  


Terms of Use

One of the best things about LOINC is that it is available for use worldwide at no cost. Anyone can download it, use it, and even re-distribute it if they wish. The details of the license are available at
The LOINC license permits both commercial and non-commercial usage, with a few stipulations about attribution and a prohibition against changing or using LOINC content to create another vocabulary standard. We know you wouldn’t want to do that because it would defeat the whole purpose of having a standard in the first place! 


Alright, let's roll up our sleeves and look at some tools to help map your local terms to LOINC.
