ISO/IEC 17025 is the internationally recognized standard for testing and calibration laboratory competence. Laboratories that achieve ISO/IEC 17025 accreditation have demonstrated to an independent accreditation body that their testing methods are validated, their staff are qualified, and their quality management systems meet rigorous requirements. For cannabis testing, accreditation provides regulators, producers, and consumers with confidence that laboratory results are accurate, consistent, and scientifically defensible. When selecting a cannabis testing laboratory, accreditation status or active pursuit of accreditation is an important indicator of a laboratory’s commitment to reliability and analytical quality.
