Biological Indicator
Biological Indicator
A biological indicator (BI) is a test system containing viable microorganisms that are used to assess the effectiveness of sterilization processes, such as autoclaving. With their ability to provide a direct measure of sterilization efficacy, biological indicators are crucial in ensuring the safety and sterility of medical instruments and equipment.
Key Features:
- Viable Microorganisms: Biological indicators contain a known population of microorganisms, such as spores, that are resistant to the sterilization process being monitored.
- Incubation: After exposure to the sterilization process, the biological indicator is incubated to allow any surviving microorganisms to grow, indicating a sterilization failure.
- Results Interpretation: Results are interpreted based on the growth or absence of growth of the microorganisms, providing a clear indication of sterilization efficacy.
- Multiple Sterilization Methods: Biological indicators are available for different sterilization methods, including steam, ethylene oxide, and hydrogen peroxide plasma.
Applications:
- Hospitals
- Clinics
- Laboratories
- Pharmaceutical Industry
- Medical Device Manufacturing
- Provides a direct measure of sterilization effectiveness, ensuring the safety and sterility of medical instruments and equipment.
- Helps healthcare facilities comply with regulatory requirements and standards for sterilization monitoring.
- Easy to use and interpret, with clear results indicating sterilization success or failure.
