The third-party labs named on the COAs we read for each vendor's lab testing count. Each page covers where the lab is, its ISO/IEC 17025 status, how to look up one of its reports and which vendors we track publish its COAs. ISO/IEC 17025 is the international standard for testing lab competence. An accreditor audits the lab against it, and the accreditation covers only the tests listed in its scope. We list facts and give no verdict on any lab. How lab testing is counted →
