In the European Union, AST products are regulated under the In Vitro Diagnostic Regulation (IVDR), which imposes stricter requirements for clinical evidence, performance evaluation, and post-market surveillance. The European Medicines Agency (EMA) and national competent authorities oversee compliance, while EUCAST (European Committee on Antimicrobial Susceptibility Testing) establishes standardized susceptibility breakpoints and testing methodologies used across member states.
In APAC, China regulates AST devices through the National Medical Products Administration (NMPA), with increasing emphasis on performance validation and quality standards.
Globally, the World Health Organization (WHO) plays a key role in setting global standards for antimicrobial resistance surveillance and susceptibility testing. WHO promotes harmonized AST methodologies, global data sharing, and stewardship frameworks to support consistent resistance monitoring and responsible antimicrobial use across healthcare systems worldwide.
