The LabServiceDefinition profile constrains the PlanDefinition resource to represent a laboratory diagnostic service for the clinicians using such services. Clinicians typically order laboratory services and use the results thereof in the course of their delivery of clinical care. 
A laboratory diagnostic service is a kind of clinical artifact that falls within the scope of PlanDefinition. It involves preparation of the patient, collection and delivery to the lab of biological/digital specimens , tests and panels performed on these specimens, interpretation of the results by the pathologist, and delivery of the results and diagnostic report back to the ordering clinician and possibly other recipients, including the patient. PlanDefinition conveys the general properties of the lab service. It describes the usage of the service, the contexts and situations in which this service is useful, and may also detail the goals that the laboratory service contributes to, such as screening or diagnostic of a particular pathology, monitoring of a long course treatment … 
An instance of PlanDefintion, thus, represents a laboratory service. It references one or more instances of ActivityDefinition, describing the service in terms of laboratory procedures, with their input and output observations. The PlanDefinition also references the instances of SpecimenDefinition representing the kinds of specimens needed to perform the service. 
A service may be a panel or super-panel grouping other laboratory services that may also be ordered independently. In that case, the PlanDefinition of the encompassing service references the PlanDefinition resources representing the included services (relatedArtifact, type composed-of). 
Reflex tests are represented as sub-actions grouped in a logical group with behavior any, meaning that any number of members of the group may be performed. Each sub-action is associated with a trigger conveying the named event, which reflexes it. 
A definition of a laboratory diagnostic service conforming to this profile can be used in a laboratory compendium/catalog as well as in other contexts. 
A laboratory service is fulfilled through the execution of one or more laboratory procedures. The logical combinations of these procedures may be conjunctions (execute each of them) or disjunctions (execute at most one of them), or a mixture of both logical structures. The closest resource that may represent a service as a set of activities logically combined with this flexibility is PlanDefinition. PlanDefinition is therefore selected to represent a laboratory service, and the laboratory procedures needed to achieve this service are represented by instances of ActivityDefinition referenced by PlanDefinition, from logical groups defined in PlanDefinition.
