Abstract
A method to calibrate measurements of a test analyte in a test sample including measuring at least one test-light level responsive to reactions of at least one reagent group and at least one reactive test analyte in the test sample and measuring at least one control-light level responsive to reactions of at least one reagent group and at least one control analyte in a control sample. Each control analyte is a known amount of at least one reactive test analyte. The method further includes determining a presence of the reactive test analyte in the test sample based on the measured test-light levels and control-light levels. The reagent group and the reactive test analyte react by attaching to each other.
