## Resource Profile: InputObservationDefinition Profile

Official URL: http://hl7.org/fhir/uv/order-catalog/StructureDefinition/InputObservationDefinition | Version: 1.0.0
Standards status: Trial-use | Maturity Level: 2 | Computable Name: InputObservationDefinition
Other Identifiers: OID:2.16.840.1.113883.4.642.40.55.42.11

This profile constrains the base resource ObservationDefinition when referenced by ActivityDefinition.observationRequirement in the context of a catalog of laboratory services. Such a resource specifies the form of an input observation expected alongside the order of a laboratory service.

Usages:

- Refer to this Profile: Laboratory Procedure Definition
- Examples for this Profile: ObservationDefinition/example-input-observation-context-for-vitamin-d, ObservationDefinition/example-input-observation-reason-for-ordering, ObservationDefinition/example-observation-collection-duration and ObservationDefinition/example-observation-collection-volume
