ABSTRACT:
A method of detecting incomplete filling of an electrochemical biosensor by collecting a series of electrical current values when a constant electrical potential is applied across the working and counter electrodes during a preliminary burn period. The slope of a line determined by linear regression based on the series of current values is used to determine whether or not the biosensor is incompletely filled. If the line has a positive slope, the biosensor is reported to be under filled. If the slope is not positive, the correlation coefficient of the current values is used as a supplemental test to indicate whether or not the biosensor is incompletely filled.
