prøvetakingskjeden

Prøvetakingskjeden, or the chain of custody, refers to the chronological documentation or paper trail that records the sequence of custody, control, transfer, analysis, and disposition of physical or electronic evidence. It is a critical concept in legal proceedings, scientific research, and quality control processes to ensure the integrity and admissibility of samples or data. The chain of custody begins at the moment a sample or piece of evidence is collected and continues until it is presented in court or disposed of.

Maintaining a proper chain of custody is vital to prevent tampering, contamination, or loss of evidence. Each step in the process must be meticulously documented. This includes who collected the sample, when and where it was collected, who handled it subsequently, when and why transfers occurred, and what analyses were performed. Signatures and dates are typically required at each transfer point. Any breaks or gaps in the chain of custody can raise doubts about the reliability of the evidence, potentially leading to its exclusion from legal proceedings or the invalidation of research findings.

The specific requirements for a chain of custody can vary depending on the jurisdiction and the type of evidence. However, the fundamental principle remains the same: to provide an unbroken and verifiable record of the evidence's handling. This ensures that the evidence presented is the same evidence that was originally collected and that its integrity has been maintained throughout the entire process.
