The laboratory uses an accession number to identify a specimen throughout the testing process. This unique identifier allows the laboratory to track and manage the specimen from the time it is received until the test results are reported. The accession number helps to ensure accurate and efficient handling of specimens and helps to prevent mix-ups or errors in the testing process. It is an essential component of laboratory workflow and helps to maintain the integrity and traceability of specimens.
