  • Determination of plasma total and unbound bilirubin using zone fluidics
    Patent number: 7416896
    Abstract: A method for determining total and bound plasma bilirubin. The method utilizes zone fluidics to enable accurate determination of the bilirubin using small volumes of sample and reagents, and significantly reduces dilution errors caused by inherent changes in bilirubin-binding with sample dilution, as well as the effects of weak bilirubin-binding competitors.
