description | To promote interoperability and adoption through common implementation, this profile sets minimum expectations for the Observation resource to record, search, and fetch body temperature observations with a standard LOINC code and UCUM units of measure. It is based on the US Core Vital Signs Profile and identifies the *additional* mandatory core elements, extensions, vocabularies and value sets which **SHALL** be present in the Observation resource when using this profile. It provides the floor for standards development for specific uses cases. | The number of weeks the subject was pregnant when a given illness began. | Values Differ
