Why is it important to maintain a chain of custody for samples collected during an assessment?

Maintaining a chain of custody for samples collected during an assessment is crucial to ensure the integrity and credibility of the test results. A chain of custody is a documented process that tracks the handling of specimens from the moment they are collected until they are analyzed. This documentation provides a clear record of who collected the samples, how they were transported, and who analyzed them.

By maintaining this thorough record, it helps to prevent contamination, tampering, or any alterations that could affect the accuracy of the results. If there are questions or disputes regarding the findings, a well-documented chain of custody serves as evidence that the samples were handled properly and that the results are trustworthy. This is particularly important in legal contexts or when public health is involved, as any compromise could lead to significant health risks or legal implications.

While other factors like compliance with insurance requirements may be a consideration, they are not the primary reason for establishing a chain of custody, which fundamentally revolves around ensuring the reliability of the testing process.
