It is important to be able to trace samples from collection to data reporting so that the utmost confidence can be placed in the analytical results. A chain-of-custody form is a mechanism for tracing the lineage of a sample from the time of collection through reporting of results to sample disposal.
The sampler initiates the chain of custody. As samples are passed from individual to individual, the transfers are noted. This process continues until the samples are delivered to the laboratory where the chain of custody form is signed, evidencing the date and time of sample receipt. The original chain of custody form is returned to the client with the analytical report, and a copy is retained with the project file by Galson Laboratories.
We have created an instructional video that provides step-by-step instructions for filling out the Chain of Custody form.
