Biological indicators play a crucial role in ensuring that sterilization processes are effective. They contain specific microorganisms that are resistant to the sterilization technique being used, such as steam, ethylene oxide, or dry heat. By exposing these indicators to the sterilization process, practitioners can determine whether the conditions were sufficient to kill the microorganisms. If the biological indicator shows no growth after the process, it confirms that the sterilization was successful. This provides a vital assurance of safety, especially in medical and tattooing environments where proper sterilization is essential to prevent infections and cross-contamination.

In contrast, measuring the size of instruments, monitoring temperature, and recording the cleaning process do not directly assess the sterilization effectiveness. These activities are important in their own right but do not provide the same level of confirmation regarding the actual elimination of viable microorganisms.
