Case: Company X requested bioburden testing for their product (suture) which will be sterilized by EO. As is routine, the correction factor determination test using repetitive method was conducted first before bioburden testing can be performed. The results showed high correction factor (CF) value, >15.0 corresponding to a low bioburden recovery efficiency percentage. When this CF value was applied to their bioburden results, the bioburden level was higher than expected. This

In membrane filtration, one common practical question is whether the membrane must be pre-wetted with saline before filtering a sample. This is especially relevant in microbiological testing and bioburden analysis, where filter performance and organism recovery are important considerations. Kumpulan Saintifik (KSFE). (n.d.).

Bioburden, the population of viable microorganisms found on a medical device, pharmaceutical raw material, or product prior to sterilization; is a critical parameter in medical device manufacturing. Determining the precise bioburden is essential for validating sterilization processes, ensuring product safety, and complying with stringent regulatory standards. The "best" testing method is not a one-size-fits-all solution; rather, it is a strategic choice based on the sample’s

In the medical device industry, maintaining high standards of quality is a necessity. Among the various components of quality assurance,...
