All IVIGs are not the same; the process makes the product2

Each IVIG manufacturer has its own unique process

Each IVIG manufacturer has its own unique:

  • Production process
  • Pathogen elimination methods
  • Final formulation and composition

This makes each product different

For this reason, clinical outcomes, including both safety and efficacy, might also differ among brands2

Dual inactivation (pasteurization and solvent/detergent treatment) and nanofiltration (20 nm) provide peace of mind for you and your patients3-5

The Flebogamma® DIF production process includes 3 validated specific pathogen-elimination steps, providing a broad safety margin4,5

Steps in pathogen elimination

In addition to these 3 validated specific steps, the process involves 4 validated non-specific pathogen reduction steps (fraction I precipitation, incubation during fraction II and III precipitation, PEG precipitation, and acid pH treatment)4,5
