  • Method for diagnosing irritable bowel syndrome and monitoring inflammatory bowel disease
    Patent number: 7892762
    Abstract: A method for aiding in differentiating irritable bowel syndrome from inflammatory bowel disease by determining the level of total endogenous human lactoferrin in clinical specimens, such as feces, mucus and bile, wherein an elevated level of lactoferrin substantially precludes diagnoses of IBS and other noninflammatory etiologies, and a kit usable in such method are provided. Further provided is a method for quantitating the level of total endogenous human lactoferrin in clinical specimens, such as feces, mucus and bile, to monitor gastrointestinal inflammation in persons having inflammatory bowel disease.
    Type: Grant
    Filed: June 17, 2009
    Date of Patent: February 22, 2011
    Assignee: Techlab, Inc.
    Inventors: James Hunter Boone, David Maxwell Lyerly, Tracy Dale Wilkins, Richard Littleton Guerrant
