  • Methods for performing fibrinogen assays using dry chemical reagents containing ecarin and magnetic particles
    Patent number: 6165795
    Abstract: A method of performing a fibrinogen assay is provided using an assay reagent containing ecarin to give an assay that is insensitive to the presence of heparin and insensitive to hematocrit, while being useful as a point of care assay in both a dry chemistry and wet chemistry format.
    Type: Grant
    Filed: June 25, 1998
    Date of Patent: December 26, 2000
    Assignee: Cardiovascular Diagnostics, Inc.
    Inventors: Patrick D. Mize, William B. Studabaker
  • Polychlorinated biphenyls (PCB) immunoassay method, its components and a kit for use in performing the same
    Patent number: 5858692
    Abstract: An immunoassay method that integrates a sample processing component that enables the testing of a variety of environmental matrixes and the components for performing the method, wherein the immunoassay utilizes a monoclonal anti-PCB antibody to detect the presence or absence of PCB based contamination in a sample when tested in a field or laboratory location.
    Type: Grant

  • Methods for the rapid detection of toxic halogenated hydrocarbons and kits useful in performing the same
    Patent number: 5547877
    Abstract: Methods for the detection, identification and/or quantitation of halogenated hydrocarbons in aqueous samples and kits for performing the methods are provided which provide high sensitivity and can provide high selectively for individual halogenated hydrocarbons such as TCE or THMs. An additional method is provided for the sensitive determination of TTHM in an aqueous sample. These methods use a general two step procedure of (1) extracting and concentrating the halogenated hydrocarbons from the aqueous sample and (2) subjecting the concentrated halogenated hydrocarbons to a modified Fujiwara reaction to provide chromophoric products which can be analyzed by absorption spectra of the resulting mixtures.
