What happens to a urine sample after collection?

Once a urine sample is collected, it is crucial for the integrity of the evidence to ensure proper handling and storage. Placing the sample in an evidence refrigerator is essential to maintain its viability for testing. This cold storage helps to prevent any degradation of the sample, which can occur if it is left at room temperature for an extended period. This preservation method ensures that the urine can be analyzed accurately at a later time without interference from environmental factors.

Protocols for handling biological samples, such as urine, emphasize the importance of following chain-of-custody procedures and ensuring that evidence is stored correctly. This is critical both for the reliability of the results and for maintaining the legality of the evidence in potential court proceedings. Thus, storing the sample in an evidence refrigerator aligns with best practices in forensic science and law enforcement procedures.
