Abstract:
1. A method for measuring a glucose level in a blood sample by electrochemical measurements using a glucose enzyme that can interfere with other biological compounds, including the steps of: (a) depositing the blood sample in a measuring zone of an electrochemical sensor including a reference electrode and a measuring electrode coated with a reagent including at least the glucose enzyme; (b) introducing the sensor into a measuring apparatus of a device, wherein the sensor includes the reference electrode, the measuring electrode, and a heating means that heats the measuring electrode, wherein the measuring apparatus is connected to an electrical power source and further includes an electronic circuit that imposes a variable or non-variable current, or a variable or non-variable voltage, between the electrodes and the heating means; (c) heating the measuring electrode, via the heating means, to at least two different temperatures during one measuring run, thereby obtaining a signal for each temperature; and (d) submitting the signal for each temperature obtained from the measuring electrode to a device for differentiating a signal indicative of the glucose from at least one other signal indicative of at least one other biological compound by monitoring the behavior of the apparent Michaelis constant of signals obtained as a function connected of temperature increase.
