Proficiency Testing & Inter-Laboratory Comparison Tracking
NABL requires accredited labs to regularly participate in proficiency testing (PT) or inter-laboratory comparisons — external checks that prove your lab's results are consistent with other accredited labs testing the same sample. Tracking participation, results and any corrective action is a recurring, easy-to-lose-track-of requirement without the right system.

What A LIMS Should Track For PT Compliance
- PT participation schedule — which programs your lab is enrolled in and when the next round is due
- Result submission & scoring — z-scores or equivalent performance results logged against each round
- Unsatisfactory result follow-up — root cause investigation and corrective action tracked when a PT result falls outside acceptable range
- Historical performance trends — see a test method's PT track record over multiple years at a glance
- Scope-linked PT requirements — know exactly which accredited methods still need a current PT round
Why PT Records Get Assessors' Attention
A lab that can't immediately produce its PT history — or worse, has an unresolved unsatisfactory result — raises a red flag fast in an assessment. Keeping this inside the same system as your sample and calibration records means nothing falls through the cracks between renewal cycles. See it live in our NABL LIMS platform.
Frequently Asked Questions
How often does NABL require proficiency testing participation?
Requirements vary by test method and accreditation scope — your LIMS should track the specific schedule your lab is required to follow per method.
What happens if a PT result comes back unsatisfactory?
It needs a documented root cause investigation and corrective action, which an assessor will expect to see evidence of — a dedicated tracking module keeps this from being missed.
Can PT history be reviewed for a specific test method quickly?
Yes, PT performance history is tracked per method, so multi-year trends are visible instantly during a review or assessment.
