If a sample arrives at the lab with no CCF, what may happen?

When a sample arrives at the lab without a Chain of Custody form (CCF), the most appropriate and likely outcome is that the sample will be invalidated, necessitating a repeat collection. The Chain of Custody form is crucial as it documents the handling and transfer of the sample from the collector to the lab, ensuring its integrity and authenticity. Without this documentation, there is no way to verify that the sample has been collected correctly or has not been tampered with. This invalidation protects the integrity of the testing process and ensures that results can be trusted, emphasizing the importance of maintaining strict protocols in drug testing and sample collection environments.
