Following a 2016 accreditation of Shuwen Biotech’s central lab, Shuwen Guanz Diagnostic Lab Co., Ltd, Shuwen has announced that it has successfully passed the 2018 biannual review and was awarded a two-year extension of the CAP accreditation.

Certification from The College of American Pathologists (CAP) is recognized as the global standard for laboratory quality management and technology in various international medical organizations, and has become the "gold standard" in the field of international laboratory medicine. Reports issued by CAP-certified laboratories meet US FDA requirements in the regulatory processes for new drugs to be marketed in the United States.
