Laboratories increasingly combine LIMS and electronic records to trace samples, instrument output, review steps and approvals. A well-designed audit trail improves trust and reduces rework.

Key building blocks

• Unique IDs: consistent sample identification through intake, testing and retention.
• Role-based access: permissions and logs that prevent unauthorized changes.
• Report versioning: revision reasons and history are transparent and searchable.

Start with high-frequency or high-risk workflows, stabilize, then scale across the lab.
