    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： The present invention provides a sensor for detecting or quantifying a target substance contained in a liquid sample. The sensor comprises a quinone compound that accepts electrons released as a result of dehydrogenation or oxidization of the target substance by the enzyme; and at least a pair of electrodes, wherein the quinone compound contains a quinone and a substituent, wherein the substituent is hydrophilic. The quinone compound has a lower redox potential than conventional substances, so interfering substances have less effect on detection results with this sensor, particularly the redox potential of the quinone compound measured using a silver/silver chloride (saturated potassium chloride) electrode as a reference electrode is more negative than the oxidization potential of ascorbic acid.

    摘要： A method and device are provided for measuring a level of a clinically relevant analyte (such as glucose) in a fluid (such as blood). The device includes a flow path for conducting said fluid through the device; a detection chamber arranged on said flow path; and detector means arranged to detect analyte levels in the fluid in said chamber, wherein:; said detection chamber contains a predetermined amount of an analyte such that that analyte mixes with fluid in the detection chamber to form, at the detector means, a calibration sample of the fluid at a time after the arrival of the fluid in said detection chamber, and said detector means is arranged to detect a first analyte level of an unadulterated sample of the fluid at a first time which is before the formation of said calibration sample and to detect a second analyte level of said calibration sample at a second time which is after the formation of said calibration sample.

    摘要： An electrochemical test device for determining a concentration of one or more analytes in a fluid sample is provided. The electrochemical test device comprises a set of electrodes including two or more working electrodes, each working electrode for determining the concentration of a corresponding analyte, and sensing chemistry for each working electrode, wherein the sensing chemistry for a first of the two or more working electrodes comprises a diaphorase, an electron transfer agent, an NAD(P)+-dependent dehydrogenase and a cofactor for the NAD(P)+-dependent dehydrogenase, wherein at least some of the diaphorase for the first working electrode is disposed in a diaphorase-containing layer which extends over the first working electrode and at least a second of the two or more working electrodes.
