Relationship between Observable Entities and NPU codes

Nomenclature, Properties, and Units (NPU) is a coding system and terminology for identification and communication of examination results from clinical laboratories. Please see their website for more information:  NPU terminology.

Logically there is a relationship between NPU and SNOMED CT observable entities. A pilot project examined overlaps and possible alignment; further work may be done. However, there is no formally maintained SNOMED CT documentation on this alignment.
