Biological indicators should be tested weekly and every time a new sterilizer is used to ensure the effectiveness of the sterilization process. This practice is crucial because biological indicators contain spores of highly resistant microorganisms, which are used to verify that the sterilization process can kill pathogens effectively.

Testing weekly establishes a regular verification schedule, allowing for a consistent assessment of the sterilization process. This frequency helps to identify any issues or failures in sterilization that could compromise patient safety. Additionally, testing every time a new sterilizer is introduced allows for immediate confirmation that the new device is functioning correctly and achieving the necessary sterilization parameters.

By adhering to this testing routine, healthcare facilities can maintain high standards of infection control and ensure that all sterile items are safe for patient use, thereby reducing the risk of infection and improving overall patient outcomes.
