BI Population & D-Value Verification
In the medical device industry, ensuring sterility and proper sterilization is paramount. This process involves verifying both the population of biological indicators (BIs) and their D-values, which are critical for determining the efficacy of a sterilization process.
The verification of BIs ensures that they are viable and capable of surviving under the conditions intended to be lethal during the sterilization process. The D-value is defined as the time required for a population of organisms to be reduced by 90% at a specified temperature, which provides insight into the resistance of the bioburden to the sterilization process.
The importance of this service cannot be overstated in ensuring that medical devices are safe and effective. Failure to properly validate BIs can lead to contamination issues that could result in device malfunction or patient harm. This service is particularly critical for regulatory compliance, as it aligns with various international standards such as ISO 11135-2 and ASTM F739.
Our team at [Lab Name] has extensive experience in this area, providing comprehensive testing services that are tailored to the unique needs of the medical device industry. Our laboratory is equipped with state-of-the-art instrumentation and adheres strictly to recognized standards to ensure accurate and reliable results.
The process begins with the selection and preparation of the biological indicators according to the intended use and sterilization method. Once prepared, these BIs are subjected to a series of tests designed to assess their resistance to the sterilization process. This involves exposing the BIs to various conditions and then measuring how much they survive after exposure.
Following this initial testing phase, our team will provide detailed reports that include all relevant data points such as survivability rates, D-values, and any other pertinent information required by regulatory bodies like the FDA or EMA. These reports are essential for maintaining compliance with current good manufacturing practices (cGMP) and ensuring product safety.
In addition to these standard tests, we also offer customized solutions that cater specifically to your organization's requirements. Whether you need additional testing parameters or specialized reporting formats, our goal is always the same—to provide you with the information necessary for making informed decisions about your sterilization processes.
