LOINC Committee

To help guide the overall LOINC development, Regenstrief organized the LOINC Committees. The LOINC Committees serve a number of key roles in LOINC development. As a group, the Committees define the overall naming conventions and policies for the development process. In collaboration with Regenstrief and other stakeholders, the Committees helps set priorities for new content development.
