REDUCE RISK. INCREASE CONSISTENCY. The Diagnostics Elite program is more than just a set of raw materials. It is an investment in your future product security. Diagnostics Elite Program Attributes: Increased control over manufacturing processes to ensure consistent product performance Enhanced change control notification Supply chain control and transparency Extensive documentation to meet current requirements Elevated quality and supply chain support We understand that developing and manufacturing IVD assays is a complex process involving critical raw materials that can affect assay performance. We also recognize that IVD industry regulations are complex and evolving. In such an environment, small inconsistencies in raw materials can lead to significant disruptions in assay design, delays in manufacturing, and affect assay performance. It is why we have developed Diagnostics Elite, an enhanced portfolio of raw materials that promotes consistency across your entire assay manufacturing process. Every Diagnostics Elite raw material is designed with a focus on improving manufacturing efficacy while minimizing your level of risk.

CONSISTENCY AND TRANSPARENCY Change Control Notification Program Our commitment to maintaining consistent manufacturing processes for Diagnostics Elite and GMP products. We understand that changes in critical raw material may require an IVD manufacturer to perform extensive impact analysis and validation. To reduce this risk and communicate changes in a timeframe that would limit the impact to commercialization, we have implemented advanced change control for Diagnostics Elite and GMP products. When changes are unavoidable, we are committed to providing you with advanced notification as quickly as possible. See Notifiable Events below for more details.
