A2LA offers three primary service lines to support recognition of competence in conformity assessment industries.

Accreditation

Accreditation is synonymous with both quality and competence of an organization, based on international standard(s). Accreditation refers to recognition given to an organization by an authoritative body such as A2LA. It is a process by which an authoritative body gives formal recognition that a Conformity Assessment Body (CAB) fulfills specified requirements and is competent to carry out specific tasks.

Accreditation is the most appropriate way to ensure an organization’s competence to perform a specified task. By encompassing the human element of the CAB, end-users can be sure that their data is accurate and dependable. A2LA is a third-party body that performs accreditations to various international standards, ensuring an unbiased and objective evaluation of your organization’s functions. A2LA provides a range of accreditation programs using international standards, including:

ISO/IEC 17025 for Testing/Calibration Laboratories                                   ISO 15189 and CLIA for Clinical Testing Laboratories

ISO/IEC 17020 for Inspection Bodies                                                             ISO/IEC 17043 for Proficiency Testing Providers

ISO/IEC 17065 for Product Certification Bodies                                           ISO 17034 for Reference Material Producers

ISO 20387 for Biobanking Facilities
