ISIA Certified Traceability

The International Serum Industry Association (ISIA) has established industry standards to aid sera users in substantiating the traceability of serum products. The ISIA has implemented a rigid program of independent audits to verify compliance with traceability standards. ISIA Traceability Certification is awarded to those that demonstrate full compliance with ISIA guidelines and are the subject of a successful audit. Further, the ISIA has established strict guidelines for product quality testing and reporting on documents like Certificates of Analysis (CoA). Sera users should source exclusively from ISIA-certified companies to ensure traceability.

Oritain Partnership:

Avantor is part of Oritain database. The Oritain verification of product origin provides enhanced traceability and trust for Avantor® Seradigm Fetal Bovine Serum (FBS). Oritain's independent, scientific sampling and analysis provides added confidence for customers using Seradigm FBS. By partnering with Oritain, we are able to verify the “fingerprint” of FBS origin exclusive to the source material country of origin. Confirmation by individual lot can be found on the product Certificates of Analysis (COA).
