  • Electrochemical methods and devices for amending urine samples for immunosensor detection
    Patent number: 10234450
    Abstract: The present invention is directed to methods and devices for amending undiluted and partially diluted urine samples in a manner suitable for performing immunoassays for target analytes, for example NGAL. Generally, the urine sample is treated with reagents including at least one of buffer materials, water soluble proteins, urease, and other interferent mitigants. These reagents control the pH of the urine sample in a manner suitable for immuno-binding reactions and ameliorate interferences, particularly during the detection step.
    Type: Grant
    Filed: March 29, 2017
    Date of Patent: March 19, 2019
    Assignee: Abbott Point of Care Inc.
    Inventors: Katrina Di Tullio, G. Bruce Collier, John Lewis Emerson Campbell
