Search labs in United StatesAmerican Association for Laboratory Accreditation (A2LA) is the primary accreditation body issuing ISO/IEC 17025 accreditation for testing laboratories in United States.
ISO/IEC 17025 is the international standard for the competence of testing and calibration laboratories. Accreditation to this standard provides independent confirmation that a laboratory operates a quality management system and is technically competent to produce valid results within its declared scope.
