Why is chain of custody important for specimens?

• A. To ensure sample integrity and traceability from collection to analysis.
• B. To expedite laboratory processing.
• C. To anonymize the patient.
• D. To reduce the need for documentation.

Answer: (A)

Maintaining a documented, verifiable path for a specimen from collection through analysis ensures its integrity and credibility. The chain of custody records who collected the sample, when and where it was collected, how it was labeled and stored, and every transfer or access along the way. This creates an auditable trail that helps detect tampering, contamination, or mix-ups and ensures the specimen being tested actually comes from the patient and remains in the same condition as when it was collected.

That clear, traceable path is why the best answer focuses on preserving sample integrity and traceability from collection to analysis. If the chain is broken, results can be questioned or deemed unreliable, which undermines clinical decisions and legal or regulatory requirements.

Expedited processing, anonymizing the patient, or reducing documentation aren’t the purposes of chain of custody. In fact, maintaining the chain requires thorough documentation and careful handling to preserve provenance and validity.
