Chain of Custody Forms

A Chain of Custody (CoC) form is a document used to track the handling and movement of samples or evidence from the moment they are collected until they are analyzed or stored. It records key details like who collected the sample, when, where, and every transfer or change of possession in between. This ensures the integrity, accountability, and traceability of the sample, preventing tampering or contamination. CoC forms are essential in forensic, environmental, and testing contexts, providing a documented chain of ownership that supports the validity and reliability of results.
