For Observation: This field houses the verbatim value from the source data representing the unit of the Observation that occurred. This code is mapped to a Standard Condition Concept in the Standardized Vocabularies and the original code is stored here for reference. - For Specimen: This unit for the quantity of the specimen, as represented in the source. - For Device Exposure: This field houses the verbatim value from the source data representing the unit of the Device. For example, blood transfusions are considered devices and can be given in mL quantities. This code is mapped to a Standard Condition Concept in the Standardized Vocabularies and the original code is stored here for reference. Using the blood transfusion example, blood transfusion is represented by the DEVICE_CONCEPT_ID and the unit (mL) would be housed in the UNIT_SOURCE_VALUE and mapped to a standard concept in the unit domain. - For Measurement: This field contains the exact value from the source data that represents the unit of measurement used. This value corresponds to a standardized CONCEPT_ID found in UNIT_CONCEPT_ID and in the 'Unit' domain within the Standardized Vocabularies. The original code is retained here for reference purposes.
