  • Patent number: 11280788
    Abstract: Described is an assay for diagnosing an infection such as peritonitis in a subject. The assay includes a binding molecule, such as an antibody that specifically binds to an inflammatory marker in a sample from the subject, and a second binding molecule that binds to a marker indicative of a pathogen in the sample. For diagnosing peritonitis in a subject, the pathogen will be at least one bacterium and/or fungus. Typically, the assay will be incorporated into a lateral flow device and may include a binding molecule that specifically binds to an antigen indicative of the presence of a specific pathogen species. The described assay(s) may further include filter(s), enriching antigen(s), and buffer(s). Also described are methods of diagnosing and treating peritonitis in a subject who is a peritoneal dialysis patient that include utilizing the herein described assay(s) or assay kit(s) to analyze the subject's peritoneal dialysis effluent.

  • Publication number: 20220026426
    Abstract: Described are assays, associated assay kits, and associated methods for diagnosing an infection in a subject. The assay includes a first binding molecule that specifically binds an inflammatory marker (i.e., neutrophil gelatinase-associated lipocalin (NGAL) homodimer) in a sample taken from the subject, and a second binding molecule that binds a marker indicative of the presence of a pathogen in the sample. The assay and methods are for the diagnosis of peritonitis in peritoneal dialysis patients.
