What is the primary purpose of maintaining a chain of custody for forensic specimens?

The primary purpose of maintaining a chain of custody for forensic specimens is to track who handles the specimen. This process is critical in forensic science because it documents the handling of evidence from the time it is collected until it is presented in court. A clear chain of custody ensures that the specimen has not been altered, tampered with, or contaminated at any point in time. This documentation provides a clear, accountable record that protects the integrity of the evidence and supports its admissibility in legal proceedings.

Maintaining this meticulous record is essential to uphold the standards of forensic analysis and protect against challenges to the validity of the evidence. By tracking every individual who comes into contact with the specimen, it provides a trail that can affirm the reliability and authenticity of the findings derived from the specimen.
