Comprehensive clinical terminologies such as SNOMED CT tend to overlap with specialized terminologies such as LOINC (e.g., for the domain of laboratory procedures). Terminological systems such as the UMLS are often used to bridge between terminologies. However, the integration of LOINC in the UMLS and with other terminologies remains suboptimal. We mapped concepts for laboratory tests from LOINC to pre-coordinated SNOMED CT concepts, based on shared relations to other concepts. As LOINC is finer-grained than SNOMED CT, several LOINC codes tend to map to the same SNOMED CT concept. However, a large proportion of LOINC codes could not be mapped to SNOMED CT through this approach, because of underspecified definitions in SNOMED CT and a lack of fine-grained, pre-coordinated concepts in SNOMED CT.
诸如SNOMED CT之类的综合临床术语往往与诸如LOINC之类的专业术语重叠（例如，在实验室程序领域）。诸如UMLS之类的术语系统经常用于在术语之间架起桥梁。然而，LOINC在UMLS中以及与其他术语的整合仍然不够理想。我们基于与其他概念的共享关系，将LOINC中的实验室测试概念映射到预协调的SNOMED CT概念。由于LOINC比SNOMED CT粒度更细，几个LOINC代码往往映射到同一个SNOMED CT概念。然而，由于SNOMED CT中的定义不够明确，且SNOMED CT中缺乏细粒度的预协调概念，通过这种方法，很大一部分LOINC代码无法映射到SNOMED CT。
