International Patient Summary Implementation Guide
1.1.0 - CI Build International flag

International Patient Summary Implementation Guide, published by HL7 International / Patient Care. This guide is not an authorized publication; it is the continuous build for version 1.1.0 built by the FHIR (HL7® FHIR® Standard) CI Build. This version is based on the current content of https://github.com/HL7/fhir-ips/ and changes regularly. See the Directory of published versions

Resource Profile: Observation Results: laboratory (IPS)

Official URL: http://hl7.org/fhir/uv/ips/StructureDefinition/Observation-results-laboratory-uv-ips Version: 1.1.0
Standards status: Trial-use Maturity Level: 2 Computable Name: ObservationResultsLaboratoryUvIps

This profile constrains the Observation resource to represent results produced by laboratory tests or panels/studies in a patient summary.

This observation may represent the result of a simple laboratory test such as hematocrit or it may group the set of results produced by a multi-test study or panel such as a complete blood count, a dynamic function test, a urine specimen study. In the latter case, the observation carries the overall conclusion of the study and or a global interpretation by the producer of the study, in the comment element; and references the atomic results of the study as “has-member” child observations.

This profile constrains the Observation resource to represent a laboratory in vitro diagnostic test or panel/study. In case of a panel/study, the results of the panel appear as sub-observations. In this case this top-level Observation acts as a grouper of all the observations belonging to the panel or study. The top-level observation may carry a conclusion in the value element and or a global interpretation by the producer of the study, in the comment element.
