  • Methods for detecting vitamin D metabolites by mass spectrometry
    Patent number: 7972867
    Abstract: Provided are methods of detecting the presence or amount of a vitamin D metabolite in a sample using mass spectrometry. The methods generally comprise ionizing a vitamin D metabolite in a sample and detecting the amount of the ion to determine the presence or amount of the vitamin D metabolite in the sample. Also provided are methods to detect the presence or amount of two or more vitamin D metabolites in a single assay.
    Type: Grant
    Filed: March 21, 2006
    Date of Patent: July 5, 2011
    Assignee: Quest Diagnostics Investments Incorporated
    Inventors: Nigel Clarke, Brett Holmquist, Gloria Kwangja Lee, Richard E. Reitz
  • Methods for detecting catecholamines by mass spectrometry
    Patent number: 7952068
    Abstract: Provided are methods for determining the amount of one or more of one or more of epinephrine (E), norepinephrine (NE), and dopamine (D) in a sample using mass spectrometry. The methods generally involve ionizing one or more of E, NE, and D in a sample and detecting and quantifying the amount of the ion to determine the amount of one or more of E, NE, and D in the sample.

  • LIPOPROTEIN ANALYSIS BY DIFFERENTIAL CHARGED-PARTICLE MOBILITY
    Publication number: 20080305549
    Abstract: The invention provides methods of preparation of lipoproteins from a biological sample, including HDL, LDL, Lp(a), IDL, and VLDL, for diagnostic purposes utilizing differential charged particle mobility analysis methods. Further provided are methods for analyzing the size distribution of lipoproteins by differential charged particle mobility, which lipoproteins are prepared by methods of the invention. Further provided are methods for assessing lipid-related health risk, cardiovascular condition, risk of cardiovascular disease, and responsiveness to a therapeutic intervention, which methods utilize lipoprotein size distributions determined by methods of the invention.
