Bioburden Testing & Microbiological Limit Testing
Bioburden Testing is a critical microbiological analysis that quantifies the total number of viable microorganisms (bacteria and fungi) present on raw materials, components, or finished medical devices. This testing plays a vital role in production process control, helping manufacturers determine the appropriate sterilization method and dose (e.g., ethylene oxide, gamma irradiation, or steam sterilization). By assessing bioburden levels, manufacturers can ensure sterilization efficacy, minimize the risk of microbial contamination, and comply with regulatory requirements for product safety.
Microbiological Limit Testing is a fundamental quality control measure designed to assess the microbial contamination levels in medical devices, particularly non-sterile products that do not undergo terminal sterilization. This testing evaluates both quantitative and qualitative microbial limits to ensure products meet stringent safety requirements for clinical use.
Our Service
Meditronics (a brand of STEMart) conducts Bioburden Testing in compliance with ISO 11737-1 and USP <61>, utilizing methods such as:
- Membrane Filtration
- Plate Count
- Most Probable Number (MPN)
For Microbiological Limit Testing, we adhere to ISO 11737-2, USP <62>, and pharmacopoeial standards (e.g., EP, JP, ChP), performing comprehensive analyses including:
- Total Aerobic Microbial Count (TAMC)
- Total Anaerobic Microbial Count (TAnMC)
- Total Yeast and Mold Count (TYMC)
- Specified Pathogen Screening (e.g., Staphylococcus aureus, Pseudomonas aeruginosa, Escherichia coli)
Prior to testing, we perform method suitability testing to:
✓ Confirm accurate microbial recovery rates;
✓ Validate neutralization of antimicrobial properties;
✓ Establish appropriate sample preparation techniques;
✓ Ensure compliance with FDA's 21 CFR Part 211.165(e).
Meditronics's testing protocols are tailored to your product's risk classification and intended use, ensuring appropriate microbial control strategies are implemented throughout the product lifecycle, therefore helping manufacturer:
✔ Demonstrate product safety for end-users;
✔ Prevent costly recalls due to microbial contamination;
✔ Accelerate time-to-market for new medical devices;
✔ Maintain compliance with evolving global regulations.
