Why Biological and Chemical Indicators are Crucial for Sterilization?

Sterilization is one of the most critical stages in ensuring patient safety in the healthcare sector. However, to understand if sterilization is truly successful, the use of sterilization control products is mandatory. This process is essentially based on biological and chemical indicators. When used correctly, these indicators safeguard sterilization processes in healthcare centers while ensuring compliance with international standards.

What is a Biological Indicator? (BI)

A biological indicator (BI) is the most reliable test method used to measure the efficacy of sterilization. It contains bacterial spores that are most resistant to sterilization processes.

  • Performs sterilization validation using actual microorganisms.

  • Operates in compliance with EN and ISO standards.

  • Provides reliable results for steam, plasma, and ethylene oxide sterilization.

  • Plays a critical role in preventing hospital infections.

What is a Chemical Indicator? (CI)

Chemical indicators are control strips that provide results through color change, indicating whether sterilization parameters have reached the correct levels.

Advantages of Chemical Indicators:

  • Provides instant sterilization control during the cycle.

  • Allows for internal/external control for every package.

  • Offers options suitable for steam, plasma, and EO sterilization.

  • Strengthens traceability and validation processes.

Should Biological and Chemical Indicators Be Used Together?

For a sterilization cycle to be considered safe:

  • Chemical Indicator: Shows that the parameters have reached the correct levels.

  • Biological Indicator: Confirms that all spores have been destroyed.

  • Combined Use: When these two products are used together, the success of the sterilization is fully validated.

For this reason, the use of indicators in every sterilization cycle is recommended in hospitals, clinics, and sterilization centers.
