ISO/IEC 17025 specifies general requirements for the competence to carry out tests and calibrations, including sampling. It covers testing and calibration quality systems using standard methods and laboratory-developed or modified methods.

ANAB is recognized internationally in accrediting organizations to ISO/IEC 17025. This recognition assures global acceptance of ANAB-accredited laboratories' test reports and calibration certificates for the purposes of free trade and regulatory acceptance. ANAB maintains membership in the International Laboratory Accreditation Cooperation (ILAC) and its regional cooperation’s, IAAC and APAC. 

The CAP accredits laboratories performing testing on specimens from human beings or animals, using methodologies and clinical application within the expertise of the program. Laboratories must be appropriately licensed to perform testing when required by law.The laboratory accreditation program is available for laboratories in the United States and for international laboratories.

CLIA regulations establish quality standards for laboratory testing performed on specimens from humans, such as blood, body fluid and tissue, for the purpose of diagnosis, prevention, or treatment of disease, or assessment of health

ILAC is the international organisation for accreditation bodies operating in accordance with ISO/IEC 17011 and involved in the accreditation of conformity assessment bodies including calibration laboratories (using ISO/IEC 17025), testing laboratories (using ISO/IEC 17025), medical testing laboratories (using ISO 15189) and inspection bodies (using ISO/IEC 17020).  

Accreditation is the independent evaluation of conformity assessment bodies against recognised standards to carry out specific activities to ensure their impartiality and competence. Through the application of national and international standards, government, procurers and consumers can have confidence in the calibration and test results, inspection reports and certifications provided.
