Permission is hereby granted in perpetuity, without payment of license fees or royalties, to use, copy, or distribute the Licensed Materials for any commercial or non-commercial purpose, subject to the following terms and conditions:

  1. To prevent the dilution of LOINC’s purpose to provide a definitive standard for identifying clinical information in electronic reports, neither the Licensed Materials, nor any portion thereof, may be used for the purpose of developing or promulgating a different standard for identifying patient observations, such as, but not limited to, laboratory test results; other diagnostic service test results; clinical observations and measurements; reports produced by clinicians and diagnostic services about patients; panels, forms, and collections that define aggregations of these observations; and orders for these entities in electronic reports and messages.
  2. The name of, or any contents of, any fields in the Group 1 Artifacts shall not be changed. The contents of any fields in the Group 3 Artifacts shall not be changed. New fields may be added to the Group 1 Artifacts and Group 3 Artifacts to attach additional information to existing LOINC records.
  3. Records may be deleted from the LOINC Table or LOINC Table Core to deal with local requirements. Records also may be added to the LOINC Table and LOINC Table Core to deal with local requirements, provided that if new records are added, any new entry in the LOINC_NUM field of such new records must contain a leading alphabetic "X" so that the new codes and records cannot be confused with existing LOINC codes or new LOINC codes as they are defined in later releases, and further provided that reasonable efforts are made to submit requests to LOINC for new records to cover observations that are not found in the LOINC Table (and LOINC Table Core) in order to minimize the need for X-codes. Records deleted or added to deal with local requirements are not reflected in the official LOINC Table and LOINC Table Core maintained by the Regenstrief Institute, Inc.
  4. The Group 1 Documents, Group 2 Documents, and Group 3 Documents may not be modified, nor may derivative works be created, without the prior written permission of the Regenstrief Institute, Inc. To request written permission, please contact loinc@loinc.org.
  5. The LOINC parts and LOINC part hierarchies shall not be used in any manner except as they are presented in the Licensed Materials (and/or in other formats of distribution approved by Regenstrief Institute, Inc.) to organize, categorize, and be constituents of LOINC terms, and provide links to external terminologies. The LOINC parts and LOINC part hierarchies are subject to change, addition, modification, or deletion, without notice, and are not strictly managed under the same policies as LOINC terms.
  6. The RELMA program is provided with the full RELMA database and associated search index files, as well as the LOINC Table and other database tables comprising the RELMA database. In addition to its use with the RELMA program, the LOINC Table that is obtained with the RELMA program may be used independently and the LOINC Table also may be modified as permitted herein. The other database tables from the RELMA database or the associated search index files may not be used or modified except in conjunction with the authorized use of the RELMA program, unless prior written permission is granted by the Regenstrief Institute, Inc. To request written permission, please contact loinc@loinc.org. The RELMA program also provides access to certain internet-based content copyrighted by Regenstrief Institute, Inc. No additional permission to modify or distribute this internet-based content is granted through the use of the RELMA program.
  7. The RELMA program includes the RELMA Community Mappings feature and access to the RELMA Community Mappings feature database. Use of the RELMA Community Mappings feature and the RELMA Community Mappings feature database is subject to the following terms and conditions:
    1. The accuracy and completeness of the information in the RELMA Community Mappings feature is not verified by Regenstrief Institute, Inc. or the LOINC Committee. Neither Regenstrief Institute, Inc. nor the LOINC Committee is liable for the information provided by the RELMA Community Mappings feature. Each user accepts the risk of using the information provided by the RELMA Community Mappings feature.
    2. The information provided by the RELMA Community Mappings feature may not be copied or distributed.
    3. Access to the information provided by the RELMA Community Mappings feature may not be shared.
    4. Reasonable efforts will be made to submit new mappings back to the RELMA Community Mappings feature database. New mappings may contain the following information (as applicable):
      1. Local battery/panel/test code;
      2. Local battery/panel/test name/description;
      3. Units of Measure;
      4. LOINC code to which it is mapped;
      5. Date of mapping;
      6. Language of test names;
      7. Version of LOINC used to do the mapping; and/or
      8. Contact information.
    5. If mappings are submitted on behalf of an organization, the person submitting the mappings represents that he or she has the authority to submit the mappings.
    6. Regenstrief Institute, Inc. shall have a non-exclusive, irrevocable license, without payment or fees, to use mappings submitted to the RELMA Community Mappings feature for any and all purposes related to LOINC, RELMA, and Regenstrief Institute Inc.'s mission, including, but not limited to:

  8. LOINC codes and other information from the LOINC Table (and LOINC Table Core) may be used in electronic records and electronic messages in conjunction with laboratory test results and clinical observations without the need to include this Copyright Notice and License or a reference thereto in the message (and without the need to include all fields required by Section 10 hereof). When the LOINC code (from the LOINC_NUM field) is included in the message, inclusion of the corresponding LOINC short name (from the SHORTNAME field), the LOINC long common name (from the LONG_COMMON_NAME field), or for laboratory terms, the LOINC Display name (from the DisplayName field) in the message is encouraged (but not required) if the message provides a place for a text name representation of the code.
  9. There is no limit on the number of copies of the Licensed Materials that may be made and distributed, provided that each copy must include this Copyright Notice and License, and must include the appropriate version number of the Licensed Materials if the Licensed Materials have a version number, or the release date if the Licensed Materials do not have a version number.

A small portion of the content of the Licensed Material consists of content subject to copyright from third parties. This third party content is either used with permission or under the applicable terms of use. In all such cases, we have included the copyright notice. The copyright of the LOINC codes per se remain owned by Regenstrief Institute, Inc. and the LOINC Committee and are subject to the LOINC Copyright Notice and License.

Some included third party content requires attribution specific to a particular LOINC code or codes. Such third party content is identified in the LOINC Table and LOINC Table Core by the applicable copyright notice (up to 250 characters) stored in the EXTERNAL_COPYRIGHT_NOTICE field. In RELMA and our web-based search application (http://search.loinc.org), the third party content is highlighted as follows: When such content appears in a search result grid, the programs will display a field with a link to a page containing the copyright notice and terms of use for that content. The programs may also visually highlight the rows of these LOINC codes.

We have included third party content that allows use and distribution at least for clinical, administrative, and research purposes. The third party copyright owners generally ask for attribution of the source, allow the free use of the content for treatment, health care management, and research purposes. They generally forbid alteration of their content (e.g., survey questions and/or answers) and use for commercial purpose, which usually means the direct sale of the survey instruments. They often do allow use of their content in commercial software, medical record and other clinical database systems, and the messaging of patient information collected through the use of these instruments.
