What is Chain of Custody?

Chain of Custody refers to processes relating to and the sequence of people who handle evidence from its collection to its analysis. In the context of drug and alcohol testing in the workplace, it refers to everything from the collecting of samples for the use in testing and filing of appropriate documentation and the safe storage and transfer of those samples in the case that further laboratory analysis is required, and all the people who handle the evidence on this journey.

Why is Chain of Custody important?

Chain of Custody is important as it preserves the integrity of evidence. When testing for Drugs and Alcohol use in the workplace, robust Chain of Custody is essential to ensure there is documented evidence of the whole process (including consent) that will protect the legal requirements of both Employee and Employer should it ever be challenged.
