Which statement correctly describes urine specimen processing?

• A. Document the handling but skip chain-of-custody requirements.
• B. Document, establish chain of custody, and store in a fridge because room temperature cannot be maintained past an hour.
• C. Leave the specimen at room temperature to save time.
• D. Store the specimen at room temperature indefinitely.

Answer: (B)

Urine specimen processing centers on preserving specimen integrity and ensuring accountability from collection to analysis. This means you must document how the specimen is handled, establish chain of custody when required to show a clear, traceable path, and store the sample in a refrigerator to prevent changes that could affect results. Room temperature can’t be maintained past a short window for many urine tests because bacteria can grow and chemical compositions can change, leading to inaccurate findings. Refrigeration slows these changes and keeps the specimen stable until testing or transport. Leaving it at room temperature indefinitely or trying to skip custody steps would undermine accuracy and proper handling.
