Abstract

A method for calibrating an imager of a reagent analyzer, comprises positioning a dry reagent pad at a first read position in a field of view of the imager, the first read position illuminated by an illumination source with a first intensity, detecting a reference optical signal by the imager, indicative of a first reflectance value of the dry reagent pad at the first read position, positioning the dry reagent pad at a second read position, the second read position illuminated with a second intensity different from the first intensity, detecting a first optical signal by the imager, indicative of a second reflectance value of the dry reagent pad at the second read position, and calculating, by a processor, a calibration factor for the dry reagent pad at the second read position based on a difference between the reference optical signal and the first optical signal.
