Abstract: Sterilization indicator test packs for testing the effectiveness of a sterilization procedure are provided. Both non-challenge and challenge-type test packs are disclosed. The non-challenge test packs include generally comprise a tray for holding a sterilization indicator the tray containing an elevated rim surface defining the perimeter of the tray and a recessed trough for receiving a sterilization indicator. The rim surface includes a plurality of spaced-apart grooves along its length extending through the rim to the recessed trough; a sterilization indicator within the recessed trough of the tray; and a lid that forms a plurality of channels with the grooves in the tray such that sterilant can enter the tray through the channels and contact the sterilization indicator.

Abstract: An apparatus reads a plurality of biological indicators (BIs) to determine efficacy of a plurality of sterilization cycles. Each BI exhibits fluorescence in response to biological activity indicative of bacterial growth in the BI. A plurality of BI holders are each configured to receive one of the BIs. A carriage is controllably movable relative to the plurality of BI holders to positions proximate each of the BI holders. A fluorescence sensor is mounted on the carriage and is positioned to sense fluorescence exhibited by the BI contained in the BI vessel in the selected BI holder. A controller is coupled to the fluorescence sensor to receive a fluorescence signal and to provide an output signal indicative of the fluorescence sensed.
