  • Method for eliminating hemolysis interference in an amylase analysis
    Patent number: 5766872
    Abstract: A method for increasing the accuracy of photometric-based assays for .alpha.-amylase by subjecting a sample to a secondary interrogating beam of radiation at a wavelength distinguishable from a primary interrogating beam of radiation. The secondary interrogating beam of radiation is indicative of an interfering reaction occurring in the absence of analyte at the primary wavelength. The secondary wavelength is outside the absorption spectrum of the analyte of interest. This secondary radiation beam's absorption is proportional to the interfering reaction at the primary wavelength.
