  personOfRecord | 1..1 | Reference(BC PersonOfRecord Logical Model) | The person this entry belongs to. | |
 laboratoryObservationTopic | 1..1 | BackboneElement | The topic composition for laboratory observations. A specimen is required, anatomical location is excluded (since the specimen indicates the collection body site). Also includes a diagnostic service (indicating the type of laboratory), not present in general observations. | |
 topicCode | 1..1 | Coding | The concept representing the finding or action that is the topic of the statement. | |

| specimen | 1..1 | Reference(BC Specimen Logical Model) | A specimen is a substance, physical object, or collection of objects, that the laboratory considers a single discrete, uniquely identified unit that is the subject of one or more steps in the laboratory workflow. A specimen may include multiple physical pieces as long as they are considered a single unit within the laboratory workflow. A specimen results from one to many specimen collection procedures, and may be contained in multiple specimen containers. Specimen may have one or more processing activities. | |
| referenceRange | 0..* | http://hl7.org/fhir/us/breastcancer/StructureDefinition/cimi-topic-ReferenceRange-model | The usual or acceptable range for a test result. | |
