The chain of custody in specimen handling primarily ensures which of the following?

• A. Quick results reporting
• B. Specimen tracking procedures from point of collection to final disposition
• C. Donor confidentiality
• D. Calibration of equipment

Answer: (B)

Chain of custody is about recording every person who handles a specimen from the moment it’s collected until final disposition, with time stamps, identifiers, and secure transfer. This creates a complete, tamper‑evident trail so the test results can be tied to the exact specimen and trusted in any legal or regulatory context. The main goal is to preserve specimen integrity and accountability, preventing substitutions, losses, or contamination without being noticed.

That focus on traceability and integrity is why this is the best choice. Quick results reporting relates to turnaround time, donor confidentiality concerns privacy, and calibration of equipment concerns measurement accuracy. They’re important in their own right but address different aspects of the testing process. In practice, the chain of custody is maintained through documented custody logs, secure seals, proper labeling, and controlled transport and storage.
