The regulation of ATPs in Hong Kong involves a risk-based approach, where the level of regulatory oversight is determined by the level of risk associated with the product.

To ensure the safety, quality, and efficacy of ATPs, the DoH requires that ATPs undergo a comprehensive evaluation process before they can be authorized for use in Hong Kong. We are an accredited laboratory to provide microbial safety tests including method validation for ATPs according to the requirement of the Department of Health of Hong Kong. Our service includes sterility test (USP 71, BP Appendix XVI A, EP Chapter 2.6.1), microbiological examination for examination of cell-based preparation (BP Appendix XVI E, EP Chapter 2.6.27), bacterial endotoxin testing, microbial identification and strain typing, etc.
