Which of the following is used by the laboratory to identify a specimen throughout testing process?

A unique identifier assigned when the specimen is received is used to identify and track that specimen through every step of testing. This accession number stays with the specimen from receipt, through labeling, processing, testing, result reporting, and storage, ensuring a continuous, unambiguous link between the specimen, its order, and its results. It provides a stable, specimen-level identifier that is separate from patient identifiers. Hospital numbers identify the patient, not the individual specimen, and may vary with visits or institutions. Mnemonic codes and password IDs are not designed to serve as the master, long-term tracker for a specimen during the testing workflow.
