LOINC Mapping Guides

We have diligently created guides for using LOINC terms across six laboratory domains. As with the Guide for Using LOINC Microbiology Terms published in 2018, these new resources help laboratories map their individual tests or catalogs within these fields to appropriate LOINC terms according to current and best practices.

Each document has been written by LOINC's terminology development team and reviewed by external stakeholders and subject matter experts in each discipline. After initial review, each guide was subject to pilot testing by laboratory professionals, followed by a second external review. The end result is a thoroughly vetted guide that can be used to train individuals in mapping of lab tests to LOINC codes for interoperable data exchange.

You must be logged in using your free LOINC user ID and password to download these files. This has been done so we may inform users of updates and potential errata.
