  "description": "This profile constrains the Observation resource to represent results produced by pathology studies in a patient summary",
  "purpose": "This profile constrains the Observation resource to represent a pathology in vitro study. In case of a multiple-observation study, the results of the study appear as sub-observations. In this case this top-level Observation acts as a grouper of all the observations belonging to the 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.",
