B/F test is a fundamental component of sterility method validation performed to ensure that a product does not interfere with the detection of viable microorganisms during sterility testing.

Introduction Sterility testing is critical in the pharmaceutical and medical device industries because it ensures that products intended for patient use are free from viable microorganisms. To perform sterility testing, two commonly referenced standards are available: USP <71> Sterility Tests and ISO 11737‑2: Sterilization of Health Care Products – Microbiological Methods, Part 2: Test of Sterility performed in the definition, validation, and maintenance of a sterilization p

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

Background Sterility testing is one of the most critical steps in ensuring the safety and compliance of medical devices, pharmaceuticals, and other healthcare products. However, before sterility testing can be performed, regulatory guidelines such as USP <71> Sterility Tests and ISO 11737-2 require a preliminary check called the Sterility Method Suitability Test, commonly referred to as the Bacteriostasis and Fungistasis (B&F) Test. Why is this step so important? Because cert

Today, we’re going deeper into the microbial identification process, specifically, how to determine the source of microbial contamination in your facility. While this method doesn’t guarantee pinpoint accuracy, it offers valuable insights that can guide your environmental monitoring and root cause analysis.

This study found that after 6 days in the icebox with temperatures of roughly 20˚C, the EO recovery is still within an acceptable range. However, this does not extend to ECH and EG residues, which have a recovery rate of less than 80% after Day 1, possibly due to the increase in temperature above 10˚C.

The Bacteriostasis and Fungistasis (B&F) test is also known as the Sterility Suitability test. The test is performed on a sterile product for the purpose of finding if any inhibiting factors exist in the product which would invalidate a sterility test. The test method will therefore confirm the presence or absence of inhibitory substances in the medical devices that could affect the result of sterility test. The test is usually required during the course of validation

What is Bioburden Testing? Bioburden is the population of viable microorganisms in or on a product, water, or raw material. Bioburden test determines the number of these microorganisms present, reported as colony forming units (CFU). The test usually involves an extraction step to remove the microorganisms followed by an enumeration or culturing technique to quantify the extracted organisms.
