What is the purpose of the chain of custody in laboratory specimen handling?

The chain of custody is a documented, verifiable record of who has handled a specimen and every transfer from collection to analysis, ensuring the specimen’s integrity. By recording who took possession, when, and where the specimen has moved, it helps prevent tampering, loss, or mix-ups and makes the test results trustworthy and defensible in quality checks or legal contexts. It also provides accountability for each step in handling the specimen. While labeling ensures correct identification and temperature monitoring helps preserve the sample, these are separate aspects of specimen handling; the chain of custody specifically tracks possession and transfer to maintain the specimen’s integrity throughout its journey.
