Conceptual division of semantics among measurement observation model

Conceptual division of semantics among measurement observation model parts Observable concept Erythrocyte volume Code: Test or question to measure observable concept. May include method, units. Erythrocytes [#/volume] in Blood Manual count Model ID: Model to represent entire statement including context (date, setting, patient, etc. )

Conceptual division of semantics among measurement observation model parts, with SCT & LOINC Observable concept: Erythrocyte volume (observable entity) Test to measure observable concept: 790 -6 Erythrocytes [#/volume] in Blood by manual count Model to represent measurement
