DNA labs are required, by the national Quality Assurance Standards, to have a written procedure for documenting every step of the lab process from first receiving the evidence through the final report. The prosecutor should have the analyst explain the lab's system for receiving, documenting, and storing the evidence. Understanding this process prepares the prosecutor to meet and defeat any attacks on the chain of custody.
