  • NMR clinical analyzers and related methods, systems, modules and computer program products for clinical evaluation of biosamples
    Patent number: 8013602
    Abstract: Methods, computer program products and apparatus automate clinical NMR in vitro diagnostic analyzers. The clinical analyzer can automatically electronically monitor selected parameters and automatically electronically adjust parameters to maintain the analyzer within desired operational ranges. The clinical NMR analyzers can be configured as a networked system with a plurality of clinical NMR analyzers located at different use sites; and at least one remote control system in communication with one or a plurality of clinical NMR analyzers, the at least one remote system configured to monitor selected local operating parameters associated with a respective clinical NMR analyzer.

  • Method of determining presence and concentration of lipoprotein X in blood plasma and serum
    Patent number: 6617167
    Abstract: A method of screening a subject for the presence of lipoprotein X includes the steps of: producing a measured lipid signal lineshape of an NMR spectrum of a blood plasma or serum sample obtained from a subject; generating a calculated lineshape for the sample, the calculated lineshape being based on derived concentrations of lipoprotein components potentially present in the sample, the derived concentration of each of the lipoprotein components being the function of a reference spectrum for that component and a calculated reference coefficient, wherein one of the lipoprotein components for which a concentration is calculated is lipoprotein X; and determining the degree of correlation between the calculated lineshape of the sample and the measured lineshape spectrum of the sample.
