Maturity: Beta

  1. The LOINC Groups project is a work in progress. The contents of this file may change from release to release as we receive feedback from users and refine our processes.
  2. The contents of the file and the groupings MUST be validated by the user prior to implementation in any aspect of clinical care. We have created Groups that may be useful in specific contexts, but these Groups have not been vetted for use in either patient care or research and should be used with caution.
  3. More information on LOINC Groups is available on our website.
