Which type of risk level is associated with sterilization by filtration?

Sterilization by filtration is typically associated with high-risk level compounding. This is because the filtration process is used primarily for preparing sterile products from non-sterile components or when eliminating particulate matter from solutions. High-risk level compounding involves more complex manipulations, such as the transfer of sterile materials to sterile containers, and handling of non-sterile products that will later be sterilized.

In a sterile compounding environment, products that are prepared using filtration often require additional precautions to ensure that all potential contaminants are eliminated. This includes ensuring the integrity of the filter, which must be validated to effectively remove microbial contaminants. Therefore, the process of sterilization by filtration involves a higher degree of risk compared to other processes that may be used for lower risk level compounding, making it appropriate to categorize it under high risk.

Other classifications, such as low, medium, or very high risk, are associated with different levels of complexity and potential for contamination, but none align with the unique challenges posed by filtration sterilization as directly as the high-risk designation does.
