What are the key elements of Lot/Batch Control?

• A. Batch number, manufacture date, expiry
• B. Temperature history only
• C. A and B together
• D. Quantity, QA release status, disposition

Answer: (C)

Lot/batch control is about traceability and the lifecycle of a production run. The essential elements to capture are a unique batch/lot number for identity, the manufacturing date and expiry date to define shelf life, the quantity produced to ensure accurate inventory and use, the QA release status to show the batch passed quality checks before distribution, and the disposition to document what happened to the batch (released, quarantined, rejected, etc.). Temperature history can be important for understanding process and storage conditions, but it isn’t a defining attribute of the batch’s identity and status itself. So the complete description would include identity, dating, and lifecycle data; the options don’t fully combine all of these elements.
