Chain of custody refers to documenting every person who collected, handled, and transported a specimen, along with when, where, and how it was moved and stored. This creates an auditable trail that preserves the specimen’s identity and integrity from collection to analysis, preventing tampering or mix-ups and providing accountability if results are questioned. The emphasis is on who handled the specimen and the custody events, not on the testing steps itself. The other options miss the point: the sequence or number of tests performed describes the workflow of analysis, not who carried the specimen; claiming it’s not important ignores the need to protect accuracy and legality; and patient contact information relates to demographics, not the custody and movement of the specimen.
