What steps ensure specimen labeling and tracking across the lab to maintain traceability?

• A. Use a barcode ID on the specimen, verify two identifiers, attach requisition, document collection time and collector, and maintain chain-of-custody
• B. Write patient name on the label, no barcode required
• C. Attach requisition but do not document collection time
• D. Check patient name verbally only, no requisition

Answer: (A)

Labeling and tracking must be auditable and minimize human error from the moment the specimen is collected. Using a barcode ID on the specimen enables rapid, accurate linking of the sample to its patient and test order, and it supports automated tracking through the lab system. Verifying two identifiers—typically patient name and date of birth—ensures the specimen truly belongs to the right patient, preventing mix-ups in a busy setting. Attaching the requisition provides the clinical context and test(s) required, while documenting collection time and the collector creates a complete timing record for the preanalytic phase. Maintaining chain-of-custody records who handled the specimen, and when, and how it moved through the facility, is essential for traceability and accountability, especially if a sample is rerouted or questioned. Together, these steps create a reliable, verifiable trail from collection to result. Relying on just a written name without a barcode invites manual transcription errors; skipping documentation like collection time or relying only on verbal checks undermines traceability and can lead to misidentification or missed timing information; and not attaching a requisition or failing to document the linkage between the order and the specimen breaks the critical connection needed for proper processing and result reporting.
