Which documentation detail is essential for ensuring traceability?

• A. Allergies.
• B. Room number.
• C. Patient identifiers on both requisition and label.
• D. Physician's license number.

Answer: (C)

The essential idea is tying every specimen to the correct patient across all steps of handling so results can be accurately traced back to the right individual. To achieve true traceability, the patient identifiers on the requisition must match the identifiers on the label, ensuring the specimen is linked to the correct patient chart and test orders. This two-sided linkage creates a verifiable chain of custody from collection through reporting. Allergies, while important for safety, do not uniquely identify a patient or ensure the specimen can be correctly traced. Room number can change or be shared by multiple patients, so it isn’t a reliable identifier. A physician’s license number has no bearing on matching a specimen to a patient or a test order. In practice, you confirm two identifiers at collection (for example, name and date of birth or a medical record number) and ensure they appear consistently on both the requisition and the label before proceeding.
