The specimen resource covers substances used for diagnostic and environmental testing. The focus of the specimen resource is the process for gathering, maintaining and processing the specimen as well as where the specimen originated. This is distinct from the use of Substance which is only used when these other aspects are not relevant. Any material sample:
– taken from a biological entity, living or dead
– taken from a physical object or the environment
The current definition of the specimen resource contains only basic information about specimen containers. It does not address the recursive nature of containers or the tracking of the location of a container within its parent container (for instance: a tube in a tray in a rack in a freezer). The frequency with which these elements are tracked may depend on the context of use; general lab, bio-banking, etc.
