Claim Text:
1. A method for determining a blood glucose concentration in a blood sample, comprising: contacting the blood sample with a sensor positioned in a blood glucose meter, wherein the sensor comprises: applying a first potential between the first and second electrodes using the blood glucose meter and detecting a change in an electrical signal between the first and second electrodes to determine when the blood sample contacts the first and second electrodes, wherein detecting a change in an electrical signal between the first and second electrodes comprises detecting a voltage, current, resistance, capacitance, or combination thereof between the first and second electrodes; applying a second potential between the first and third electrodes using the blood glucose meter and determining whether a change in an electrical signal occurs between the first and third electrodes to determine whether the blood sample contacts the first and third electrodes, wherein determining whether a change in an electrical signal occurs between the first and third electrodes comprises determining whether a voltage, current, resistance, capacitance, or combination thereof occurs between the first and third electrodes; and subsequent to applying the second potential between the first and third electrodes, determining the blood glucose concentration only upon detecting the change in an electrical signal between the first and second electrodes and the change in an electrical signal between the first and third electrodes.
