Accreditation bodies such as NABL want evidence that each result was produced, checked and released by authorised people following the right process. In a paper-based lab, collecting that evidence before an assessment can take days.
What a digital audit trail records
Every action on a sample or result is saved with the user, date and time: registration, receipt, result entry, edits, approval and release.
Why it helps
- Every change to a result is visible, along with who made it.
- Approvals are tied to named, authorised staff.
- Turnaround time can be shown for any period instead of estimated.
- Records are stored securely and backed up daily.
When records are created as the work happens, audit preparation becomes a report instead of a project.
Habits that matter
Software helps, but people make compliance work. Give every staff member their own login, avoid shared accounts, and review edited results regularly. Role-based access and approval workflows make those habits easy to keep.
