| Definition | One or more specimens that the diagnostic investigation is about. |
| Control | 0..* |
| Type | Resource(Specimen) |
| Comments | Many investigation requests will create a need for specimens, but the request itself is not actually about the specimens. This is provided for when the diagnostic investigation is requested on already existing specimens. |
| DiagnosticOrder.status | |
| Definition | The status of the order. |
| Control | 0..1 |
| Binding | DiagnosticOrderStatus: The status of a diagnostic order (see http://hl7.org/fhir/diagnostic-order-status for values) |

| DiagnosticOrder.priority | |
| Definition | The clinical priority associated with this order. |
| Control | 0..1 |
| Binding | DiagnosticOrderPriority: The clinical priority of a diagnostic order (see http://hl7.org/fhir/diagnostic-order-priority for values) |

| Comments | The Order resource also has a priority. Generally, these should be the same, but they can be different, for instance in the case where the clinician indicates that the order is urgent, but the subsequent workflow process overrule this priority for some reason. The effective default value is "normal". |
