Which is NOT a reason to use a Chain of Custody for samples?

Using a Chain of Custody (CoC) is crucial in the context of sample handling and analysis. The primary purpose of a CoC is to maintain the integrity and traceability of samples throughout the entire process, from collection to analysis, and ultimately to reporting results.

The role of a CoC includes tracking the location and handling of samples, which ensures that each sample is accounted for at every stage. It also serves to document the transfer of samples between individuals or organizations, which is essential in establishing a transparent record of who handled the samples and when. Additionally, adherence to CoC protocols ensures compliance with various regulations and standards, which is vital for the validity of the results and for legal defensibility in case the data is challenged.

In contrast, providing a summary of analysis results is not a function of a Chain of Custody. Instead, a CoC focuses on the procedural integrity and documentation of the sample’s journey rather than the results obtained from the samples. The summary of analysis results pertains more to reporting and interpreting the data after testing, rather than to the chain of handling that ensures the results are credible. Hence, this option stands out as not aligning with the main objectives of maintaining a Chain of Custody.
