Resource Profile: Observation Results: laboratory

This profile constrains the Observation resource to represent results produced by laboratory tests or panels/studies for the HL7 Europe project. 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.
