Body temperature


PARAMETER CASE REPORT FORM RESPONSE OPTIONS
Body temperature ☐ Cel

This profile of a FHIR Observation is derived from the Body temperature-profile of the FHIR R4 core specification.

In addition to LOINC, Observation.code contains an exemplary SNOMED-CT coding.

Observation.valueQuantity has a fixed UCUM-unit of Cel.
