What software can and cannot do
NABL accreditation against ISO 15189 assesses your laboratory's competence: your people, your procedures, your quality system and your results. Software is a supporting tool, not a route to accreditation, and any vendor implying otherwise is overselling.
What it does do is make several categories of required evidence straightforward to produce. Assessors ask for records; a system that keeps them automatically saves a great deal of reconstruction.
Where the LIS genuinely helps
These are the areas where labs most often find their software doing real work during an assessment.
- Sample identification and traceability from receipt through to report
- A complete audit trail showing who entered, verified and released each result
- Amended report control, with the original retained and the revision marked
- Turnaround time monitoring against defined targets, with evidence over a period
- Critical value identification, notification and acknowledgement records
- Controlled report formats, so the released document is consistent
- Access control demonstrating that only authorised staff performed each role
Where it does not help
Internal quality control and external quality assessment are laboratory practices. Software can store the records and chart the results, but running the controls and acting on them is yours.
Method validation, measurement uncertainty, staff competency assessment and equipment calibration are similarly matters of laboratory practice. A LIS holds the documentation; it does not do the work.
The quality manual, standard operating procedures and the non-conformance process are yours to write and to follow.
Practical advice if you are preparing
Turn on the things you will need evidence for well before your assessment, not during preparation. Turnaround time data is only useful if it covers a meaningful period, and an audit trail is only persuasive if it has been running long enough to show routine practice.
Make sure individual logins are actually in use. An audit trail showing that every action was performed by a single shared counter account demonstrates the opposite of what you want it to.
And check that your amended report process works the way your SOP says it does. This is a common finding, and it is entirely avoidable.
