Accessioning (medical)

Accessioning in the medical sense can refer to[1][2]:

  • an ordered test or group of tests on an individual or sample item;
  • a specimen that has been formally received by a laboratory or health care service, typically receiving an accession number;
  • the act of logging or documenting the demographics and/or receipt of a specimen in the lab.

Many larger laboratories will have an accessioning area where samples are received, processed, logged, and assigned an identifier before being distributed for analysis.[3][4][5] Samples are typically logged into a LIS, LIMS, or proprietary database; given a unique identifier or accessioning number; barcoded or given an RFID tag; and even given additional preparations before storage and/or analysis. Additionally, demographic, medical, and ethical information and appropriateness (in the case of genetic tests, for example) may be researched and applied to the received sample and its corresponding database entry.[6]
