Biological Indicators for Sterilization

Biological indicators (BIs) provide information on whether necessary conditions were met to kill a specified number of microorganisms (bacterial spores) for a given sterilization process, such as Vaporized Hydrogen Peroxide (VH2O2) sterilization in V-PRO™ Low Temperature Sterilizers.

BIs are typically used within process challenge devices (PCD), designed to represent the most challenging products routinely processed for autoclave sterilization testing. A passing result for the BI within the PCD demonstrates that the sterilization cycle was effective at inactivating the BI, providing Sterile Processing Department staff with a level of assurance in their sterilization process.
