How does barcoding enhance traceability of specimens in pre-analytical handling?

• A. Provides unique identification, reduces labeling errors, enables real-time tracking and audit trails.
• B. Replaces the need to label at all.
• C. Slows down processing.
• D. Only helps after tests are completed.

Answer: (A)

Barcoding enhances traceability by giving each specimen a unique identifier that stays linked to the patient, test orders, collection details, and movement through the pre-analytical workflow. Scanning the barcode reduces labeling errors because data are captured electronically, avoiding misread handwriting or misapplied labels. Real-time scans create an auditable trail of where the specimen has been, who handled it, and when, supporting chain-of-custody and quality assurance. It also streamlines the workflow and works with automated systems, often speeding processing and reducing errors. Barcoding complements traditional labeling and is valuable during collection, transport, and accessioning, not just after testing.
