Regenstrief Institute, Inc

The Regenstrief Institute, an internationally renowned healthcare and informatics research organization, is the overall steward of the LOINC® coding system. Led by Clem McDonald, MD, Regenstrief’s informaticians initiated the LOINC effort in 1994. Regenstrief maintains the LOINC database and supporting documentation, processes submissions and edits to the content, develops and curates accessory content (descriptions, hierarchies, other attributes, etc), develops the RELMA mapping program, and coordinates LOINC releases. In addition, Regenstrief continues to cultivate the LOINC community worldwide. The LOINC effort at Regenstrief is led by Daniel J. Vreeman, PT, DPT, MSc, Associate Director of Terminology Services.  To help guide the overall LOINC development, Regenstrief organized the LOINC Committee.

LOINC Committee

The LOINC® Committee serves a number of key roles in LOINC® development. As a group, the Committee defines the overall naming conventions and policies for the development process. In collaboration with Regenstrief and other stakeholders, the Committee helps set priorities for new content development. Individual members may also take the lead on the development of naming rules and LOINC® names for new subject matter and serve as content experts to answer questions that come up with new submissions. The LOINC Committee has two primary divisions: the Laboratory LOINC Committee which deals with observations made on specimens, and the Clinical LOINC Committee which deals with observations made on patients.
