  • Electrochemical affinity biosensor system and methods
    Patent number: 8557989
    Abstract: The present invention provides novel osmium-based electrochemical species for the detection of wide variety of analytes using immunological techniques. The present invention also provides diagnostic kits and test sensors supporting electrode structures that can be used with the osmium-based electrochemical species. The test sensor can be fabricated to support interdigitated arrays of electrodes that have been designed to provide amplification of the electrical signal amplification desired to analyze analytes that may be present at low concentrations.
    Type: Grant
    Filed: September 25, 2012
    Date of Patent: October 15, 2013
    Assignee: Roche Diagnostics Operations, Inc.
    Inventors: Eric R. Diebold, Mitali Ghoshal, David Z. Deng, Jane Shiow-Chuan Tsai
  • System and methods for determining an analyte concentration incorporating a hematocrit correction
    Patent number: 8529741
    Abstract: Methods and devices for determining the concentration of a constituent in a physiological sample are provided. The blood sample is introduced into a test strip with portions of the blood sample being directed to both a first capillary and a second capillary. The first capillary configured to electrochemically determine a concentration of a first analyte in a blood sample by measuring a signal across a set of electrodes. The second capillary is configured to determine a hematocrit value of the blood sample by measuring a signal across a second set of electrodes.
