Instructions for use (IFU)

Sterile processing definition

Instructions for use are the device manufacturer's written directions for cleaning, inspecting, packaging and sterilizing a specific device. They specify things like detergents, disassembly, compatible sterilization methods and cycle parameters. In sterile processing the IFU is the first reference to check whenever there is a question about how to process a device.
