S&A Scientific Labs

How It works

Getting a compliant ILC study set up takes just four steps:

Tell us the analyte, matrix, and method you need evaluated.
We prepare a sample and assign a reference value.
You test and submit results.
You receive a performance report comparing your result to the reference value and acceptable range — suitable for your 17025 quality records.

Best Suited For: 17025-accredited labs that need a documented, standards-compliant competency check for an analyte where no accredited PT program currently exists.

**This ILC study satisfies ISO/IEC 17025 clause 7.7.2 as an interlaboratory comparison.

It is not part of S&A's A2LA accredited PT scope and should not be represented as accredited proficiency testing. **

Frequently Asked Questions

Please reach us at customerservice@sacilabs.com if you cannot find an answer to your question.

Is an ILC the same as proficiency testing (PT)?

Not exactly. PT programs are run under a formal accreditation scope (ISO/IEC 17043) with statistical evaluation across multiple labs. An ILC is a broader term — ISO/IEC 17025 (clause 7.7.2) recognizes it as an equally valid way to demonstrate competency when no accredited PT program covers your specific analyte or matrix.

Will my auditor accept an ILC in place of PT?

Yes — 17025 explicitly allows either. Your ILC report documents your result against a reference value, giving your assessor the same type of objective evidence a PT report would.

Does this affect S&A's own accreditation status?

No. The ILC is offered as a separate, clearly labeled service outside our A2LA PT scope.
