LOINC Prerelease Terms


These codes are currently under development by the LOINC team, and are subject to change prior to inclusion in a public release. It is possible that they may not be published in the next, or any, public release. They are provided here for informational purposes only.


Special Use codes are developed in response to an urgent or emergent situation. These codes are based on the most up to date information available at the time of their creation. They have undergone the normal QA terminology process. LOINC supports their use in the unique situation that resulted in their rapid creation. However, be aware that downstream users may not be ready to handle prerelease codes until they are published in an official release.
