  • Patent number: 8391940
    Abstract: Described and illustrated herein are exemplary methods of operating an analyte measurement system having a meter and a test strip. Such methods may be exemplarily achieved by determining a first glucose concentration by measuring a first reflectance at about a first wavelength at a testing surface of the pad; measuring a second reflectance at about a second wavelength; formulating at least one equation to correct the first glucose concentration for temperature or hematocrit effects using the second reflectance at about the second wavelength; determining a second glucose concentration using the first glucose concentration, the second reflectance at about a second wavelength; and displaying the second glucose concentration that is corrected for temperature and hematocrit effects.

  • Publication number: 20110120865
    Abstract: Generally, embodiments of the present disclosure relate to analyte determining methods and devices (e.g., electrochemical analyte monitoring systems) that have improved uniformity of distribution of the sensing layer by inclusion of a high-boiling point solvent, where the sensing layer is disposed proximate to a working electrode of in vivo and/or in vitro analyte sensors, e.g., continuous and/or automatic in vivo monitoring using analyte sensors and/or test strips. Also provided are systems and methods of using the, for example electrochemical, analyte sensors in analyte monitoring.

  • Publication number: 20080081969
    Abstract: The invention relates to a method for calibrating an analyte-measurement device that is used to evaluate a concentration of analyte in bodily fluid at or from a measurement site in a body. The method involves measuring a concentration, or calibration concentration, of an analyte in blood from an “off-finger” calibration site, and calibrating the analyte-measurement device based on that calibration concentration. The invention also relates to a device, system, or kit for measuring a concentration of an analyte in a body, which employs a calibration device for adjusting analyte concentration measured in bodily fluid based on an analyte concentration measured in blood from an “off-finger” calibration site.

  • Patent number: 5605837
    Abstract: A control solution for use with a photometric blood glucose strip contains glucose in an aqueous suspension of carbon black. The control solution mimics blood when applied to a whole blood glucose test strip, which is then inserted into a meter. A meter reading within a predetermined range indicates that meter and strip are operating satisfactorily. Preferably the control solution is buffered to a neutral pH and includes chloride ion to provide a stable end point for the glucose reaction. Depending on the glucose concentration, the solution checks meter and strip operation at high, low, and normal blood glucose levels.
