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. STERIS's complete portfolio of biological indicators offers testing for various applications, including steam sterilization and vaporized hydrogen peroxide (VH2O2) sterilization. Geobacillus stearothermophilus spores are mainly used in these applications due to their high resistance to these sterilization processes.

STERIS biological indicators for steam sterilization include self-contained biological indicators (SCBI) and process challenge devices or test packs. These devices play a crucial role in sterility assurance and provide the only direct measure of the lethality of the sterilization process.
