    摘要: Methods for determining a concentration of an analyte in a sample, and the devices and systems used in conjunction with the same, are provided herein. In one exemplary embodiment of a method for determining a concentration of an analyte in a sample, the method includes detecting a presence of a sample in an electrochemical sensor including two electrodes. A fill time of the sample is determined with the two electrodes and a correction factor is calculated in view of at least the fill time. The method also includes reacting an analyte that causes a physical transformation of the analyte between the two electrodes. A concentration of the analyte can then be determined in view of the correction factor with the same two electrodes. Systems and devices that take advantage of the fill time to make analyte concentration determinations are also provided.

    摘要: Described herein are systems and methods for distinguishing between a control solution and a blood sample. In one aspect, the methods include using a test strip in which multiple current transients are measured by a meter electrically connected to an electrochemical test strip. The current transients are used to determine if a sample is a blood sample or a control solution based on at least two characteristics. Further described herein are methods for calculating a discrimination criteria based upon at least two characteristics. Still further described herein are system for distinguishing between blood samples and control solutions.

    摘要: A weighing scale includes a platform supporting a load. Force transducers beneath the platform output respective transducer force signals of the load. An area sensor above the platform outputs area force signals of load forces applied to respective spatial areas of the platform. A processor is configured to determine the load's weight and location on the platform based on the transducer force signals and the area force signals. A method of weighing the load is also described. A method of monitoring the load includes measuring first transducer force signal(s) and first area force signal(s) of the load, and then repeatedly measuring second force signal(s) of the load using the transducer(s) or area sensor until the first and second signal(s) indicate a change in a weight or location of the load. A changed weight or changed location of the load is then determined using the measured second force signal(s).

    摘要: Methods of determining a corrected analyte concentration in view of some error source are provided herein. The methods can be utilized for the determination of various analytes and/or various sources of error. In one example, the method can be configured to determine a corrected glucose concentration in view of an extreme level of hematocrit found within the sample. In other embodiments, methods are provided for identifying various system errors and/or defects. For example, such errors can include partial-fill or double-fill situations, high track resistance, and/or sample leakage. Systems are also provided for determining a corrected analyte concentration and/or detecting some system error.

    摘要: Described are embodiments of a system or method configured to emit an alert indicator in response to detecting an anomalous analyte event in a patient wearing a continuous analyte monitor. Absent a response from the patient to the alert indicator, the system or method escalates the alert notifications by communicating alert messages to other alarm devices or to caregivers that may be needed to assist the patient.
