Chain of custody refers to the system of controls governing the collection, processing and storage of samples. These controls reduce the potential for samples to be accidently or maliciously tampered with and guarantee that results reported by the laboratory originate, beyond doubt, from a particular donor. In addition, chain of custody paperwork ensures accurate documentation of the process by detailing the collection, custody, transfer, storage and analysis of samples.
In regards to drug and alcohol testing, having a strict chain of custody procedure in place is essential. It maintains the protection of the sample donor who could face life-altering consequences should results be positive as well as protecting the organisation requiring the drug or alcohol test by ensuring legal viability should legal proceedings occur on the strength of the test outcome.
