| - | These relationships are defined as "LOINC - SNOMED eq" between "LOINC Hierarchy" Concepts and SNOMED Concepts representing the entity that is measured. Note that only a small fraction (1%) is currently mapped. Also, note that some of the mappings seem to confuse the testing for drugs with the drugs themselves. | + | The purpose of External LOINC relationships is the following: |

Note, the LOINC hierarchy is not connected to the SNOMED hierarchy which is the core Domain space for Measurement and Observation in OHDSI vocabularies. |
