A sterilizing cabinet performs a method of processing a medical device, such as a used medical device or an otherwise non-sterile medical device. The method includes receiving input from a user selecting a sterilization cycle from a plurality of available sterilization cycles. The sterilizing cabinet identifies a biological indicator associated with the selected sterilization cycle. The sterilizing cabinet prompts the user via a touch screen display to place the medical device and the biological indicator into a sterilization chamber of a sterilizing cabinet. The sterilizing cabinet performs load conditioning on the medical device in the sterilization chamber. The sterilizing cabinet then performs the selected sterilization cycle on the medical device in the sterilization chamber after completing the act of load conditioning.
