Previous Page - US Core ImplantableDevice

The US Core Laboratory Result Observation profile sets minimum expectations for the Observation resource to record, search, and fetch laboratory test results associated with a patient/member. It identifies which core elements, extensions, vocabularies and value sets SHALL be present in the resource when using this profile.

In US Core 6.1.0 a number of new Observation profiles were created. Many of them replaced the Vital Signs profiles from the base FHIR R4 base specification. The full list of US Core 6.1.0 Observation profiles in can be found here:

The essential fields (Must Support or Cardinality greater than 0..*) to be provided in the US Core 3.1.1 LaboratoryResultObservation or US Core 6.1.0 LaboratoryResultObservation resource are:
