Lab testing
What does ISO/IEC 17025 accreditation mean?
Written by: Author pendingReviewed by: Reviewer pendingUpdated:
That an independent accreditation body has audited the laboratory's competence, methods, equipment, staff and records for the tests in its scope, against the international standard for testing laboratories; the reports linked here cite accreditation number 85368 (ISO).
What does the standard cover?
ISO/IEC 17025 is the international standard for the competence of testing and calibration laboratories. Accreditation means a recognized body has assessed the laboratory and granted a scope listing the methods it is accredited for; the laboratory must validate its methods, including limits of quantitation, rather than assume them (ISO).
Why does the number matter?
An accreditation number lets anyone look the laboratory up with the accrediting body and confirm the scope covers the test on the report. The reports linked here print "ISO/IEC 17025:2017 Acc. 85368" in the header (NarcoBrands COAs). A report with a logo and no number cannot be checked.
Do any states require it?
Texas does. Its kratom chapter permits retailers to sell only products "tested and labeled" under the chapter, with testing at an ISO 17025 laboratory (Texas SB 497). Payment underwriters for kratom also ask for third-party laboratory results.
Is accreditation the same as a good report?
No. Accreditation says the laboratory is competent for the methods in scope; it does not add tests the client did not order. An accredited potency panel is still only a potency panel. See what is a contaminant panel.
