Data Element Information | |
Use Case Description(s) | |
Use Case Description | Often LIS are not patient centric, like EHR-s, but specimen centric, so this identifier is used as the primary key to locate all data that belongs to this specimen. To support communication between provider and lab and between lab and public health agency this identifier is very important. It must be stressed, that this identifier should be unique within the assigning authority and not reused over time (though that may still be a practice in some labs). |
Estimate the breadth of applicability of the use case(s) for this data element | This element should be associated with EVERY lab test and its related data elements, so will be in EHR-s, LIS, PHR, Surveillance system and disease registries. |

Use Case Description | This also applies to lab data exchanges between lab and providers LRI: http://www.hl7.org/implement/standards/product_brief.cfm?product_id=279 FHIR observation in US Core lab observation profile: https://build.fhir.org/ig/HL7/US-Core/StructureDefinition-us-core-observation-lab.html references the specimen, but it is not a must support element at this time; the FHIR specimen resource refers to this element as specimen.accessionIdentifier |
