The following guidelines and recommendations outline brand and asset use, including logo, colors, content, graphic elements and trademarks without negotiating legal agreements. The LOINC marks include, but are not limited to, the LOINC name, logo, and any word, phrase, image, or other designation that identi es the source or origin of any of LOINC’s products.

Because brands inevitably evolve, the below guidelines may change over time. We ask that you regularly refer back to this website for the latest. For further information, please contact us.

To make any use of our marks in a way that is not covered by these guidelines, contact us and include a visual mockup of intended use.

Regenstrief requests that you use the following guide when developing marketing, communication, training, etc. collateral. As a freely available resource, the LOINC brand depends on not only patrons of the program but also consistency of communication amongst participants globally.

Brand voice

While trademark and proper logo use are requested, we do encourage users to have fun with the LOINC brand. When creating collateral that references LOINC, consider using terms from this short dictionary:

  • LOINC (noun): as in, the database
  • LOINC (verb): To LOINC, be LOINCing (e.g. mapping your local tests to LOINC), or have LOINCed (e.g. once you’re done mapping, you have “LOINCed” all of your local tests)
  • [Head, Chief, etc.] LOINCer (noun): a person with LOINC expertise
  • LOINCification (nominalization): the process of representing an existing test or variable (or collection thereof) in LOINC

While not exhaustive, this list provides creative stimulation for LOINCifying phrases. No need to check the dictionary or for legal approval on these. Feel free to be creative and spread the LOINC love.
