Claim Text:
1. A method of using a blood glucose meter, comprising: contacting a blood sample with a sensor positioned in the 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; 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; and determining partial filling of the sample chamber by the blood sample when a change in an electrical signal occurs between the first and second electrodes and when a change in an electrical signal does not occur between the first and third electrodes.
