Scope of coverage

DEFINITION (SPECIMEN): Any material sample:

  1. taken from a biological entity, living or dead
  2. taken from a physical object or the environment

Biospecimen can contain one or more components including but not limited to cellular molecules, cells, tissues, organs, body fluids, embryos, and body excretory products (source: NCIt, modified).

The specimen resource covers substances used for diagnostic and environmental testing.

RIM scope

  • Role: Specimen (RoleClass=SPM)
    • Entity (player): Material (EntityClass="MAT")
    • Entity (scoper): Choice - Person, Non-Human Living Subject, Material)
  • Entity: Place (EntityClass="PLC")

Resource appropriateness

Specimens are primarily of importance in healthcare for diagnostic testing and in public health for environmental testing. Because of the frequent biologic nature of specimens, they are uniquely identified. Additionally, specimens are tracked, transported, and stored, sometimes for years.

Expected implementations

The Specimen resource is used by other resources such as the Diagnostic Report to record the entity that is being reported against. The Procedure resource may also reference a specimen removed during a procedure.

Content sources

  • HL7 v3 Laboratory Standard - Normative
  • HL7 v2.x
  • HL7 OO Specimen DAM Project

Example Scenarios

  • A tumour excised fram a patient during a procedure is sent for histological examination. It is referenced both in the Procedure and the Diagnostic report.
