parametric release
Sterilization validation method based solely on physical parameters rather than biological indicators.
Full Definition
Parametric release is a sterilization validation approach that relies exclusively on documented physical and chemical parameters of the sterilization process rather than biological indicators to confirm sterility. This method requires comprehensive validation demonstrating that when specific time, temperature, pressure, and other critical parameters are achieved and maintained, the sterilization process consistently delivers the required sterility assurance level. Parametric release is primarily used in industrial settings and some hospital applications where extensive validation data supports the approach. It allows for immediate release of sterilized items without waiting for biological indicator results.
Usage
Usage note: Emphasize that this method requires extensive validation and is not suitable for all facilities.
In Context
- "The facility implemented parametric release after completing extensive validation studies of their steam sterilization processes." — Quality assurance protocol
- "Parametric release criteria include achievement of 121°C for 15 minutes with documented steam quality parameters." — Sterilization validation report
