Abstract:
1. A method of analyzing a ketone body in a biological fluid sample, the method comprising: contacting an inlet region of a biosensor having multi-directional fill capabilities with the sample to provide sample into a sample chamber of the sensor, the sensor comprising: a first electrode pair, wherein electrodes of the first electrode pair are spaced in a lateral direction with respect to each other in the sample chamber, and a second electrode pair, wherein electrodes of the second electrode pair each comprise an electrode portion and a trace portion and wherein entire electrode portions of the electrodes of the second electrode pair are spaced in a longitudinal direction with respect to each other in the sample chamber, wherein the second electrode pair is positioned in between the first electrode pair, the first and second electrode pairs placed on a first surface within the sample chamber, the first electrode pair being a pair of indicator electrodes; contacting the indicator electrode pair with the sample in the sample chamber; and after contacting each electrode of the indicator electrode pair with the sample, beginning analysis of the ketone body at the second electrode pair.
