American Association for Laboratory Accreditation (A2LA)

The American Association for Laboratory Accreditation (A2LA) is a non-profit, nongovernmental, public service, membership organization dedicated to operating a nationwide, broad spectrum laboratory accreditation system. Accreditation is defined as a formal recognition of competence that a laboratory can perform specific tests or types of tests. The general requirements for accreditation used by A2LA are from the international standard, ISO/IEC Guide 25, 1990. Additional program requirements for specific fields of testing or specific programs which are necessary to meet particular user needs complement these general requirements in particular areas.
