In phlebotomy, what does chain of custody refer to, and when is it relevant?

• A. Documentation showing who collected, handled, and transported a specimen; relevant for transfusion, forensic testing, or legal investigations.
• B. A chain of custody is the order of blood draw
• C. A type of consent form
• D. A method for labeling specimens

Answer: (D)

Chain of custody is the documented, auditable trail of control over a specimen from the moment of collection through all handling, processing, transport, storage, and analysis, including who touched it, when, where it went, and under what conditions. This ensures the specimen’s integrity and accountability, which is essential when the results may be used for medical decisions, legal purposes, or regulatory scrutiny. In phlebotomy, this concept is most important in transfusion medicine, where tracking the specimen helps ensure the right patient receives the correct blood product, and in forensic or legal investigations where evidence must be shown to have been handled properly. It’s not simply about labeling, the order of the blood draw, or consent forms; those are separate aspects of specimen handling. The chain-of-custody record typically notes who collected the specimen, every transfer or handling step, dates and times, storage conditions, and who disposed of it, with signatures as needed.
