Lab
Class AccessionEvent

Accession: "An increase by means of something added to record as acquired" - Websters. Accessioning is the act of taking on the responsibility to perform a laboratory test and adding the test to the laboratory's workload (hence the word accession, the workload or responsibility has been increased). While the definition would imply a close alignment with the Lab Test Promise, in practice, the Accession (and the "Accession Number") are more closely associated with the Specimen, as the Specimen represents a unit of work. Accession numbers and specimen numbers are often related, and when a specimen is subsetted for some other purpose, a new accession number may be created. This class represents the act of creating a new accession, and is associated with both the Promise and the Specimen.

Attributes
«TS» PointInTime accessionDate accessionDate

The date/time upon which the laboratory accepted the unit of work into its workload. This date/time might be the same as the Laboratory Promise date, or the date/time that the laboratory received the Specimen(s), depending on local laboratory practice.

«II» Id accessionId accessionId

Uniquely identifies the accession. The accession is closely associated with both the Promise to perform a laboratory test, and the Specimen(s) upon which the tests are performed. The accession id therefore may be based upon the LabTestPromise.fillerOrderId or the Specimen.id, or conversely, those ids might be based upon this accessionId, depending on local laboratory practice. For example, if the accession id is ABCD, and two samples were received, one sample id might be ABCD-01 and the other ABCD-02. The accession id therefore may be used to identify the laboratory promise, samples, and results.

"This field contains accession identifier(s) associated with the specimen...." - HL7 Version 2.8, SPM-30.
"The identifier assigned by the lab when accessioning specimen(s). This is not necessarily the same as the specimen identifier, depending on local lab procedures." - HL7 FHIR, Specimen.accessionIdentifier

Specimen specimen specimen

Identifies the specimen(s) associated with the accession.
