Abstract
A biological indicator reader is provided for reading a plurality of biological indicators to determine the effectiveness of at least a sterilization process. Each biological indicator is configured to exhibit fluorescence when the sterilization process has failed. Each reader comprises a housing having a plurality of biological indicator holders, a heater coupled to the housing and configured to heat the plurality of biological indicator holders to a preselected temperature to incubate the biological indicators, a UV light emitter configured to emit UV light through a first aperture on the side of each holder and an optical detector positioned under a second aperture on the bottom of the biological indicator holder, the optical detector configured to detect fluorescence intensity indicating the effectiveness of the sterilization process. A method of using the biological indicator reader is provided. A biological indicator system and display are also provided.
