38. A sensor for determining the concentration of a ketone body in a sample of biological fluid, the sensor comprising:
-
a working electrode and a counter electrode; and a sample chamber for receiving biological fluid and which sample chamber includes at least a portion of the working and counter electrodes, wherein the sample chamber is adapted to receive the biological fluid by contacting a corner of the sensor with the biological fluid. - View Dependent Claims (39, 40, 41, 42)

60. A method for determining a ketone body concentration in a sample of biological fluid, the method comprising:
-
operatively connecting an analyte sensor with a meter; applying, after connecting the sensor to the meter, an ketone body-containing sample to a corner-fill analyte sensor by contacting a sample admitting opening positioned about a corner of the sensor with the sample; and determining the concentration of a ketone body in the sample. - View Dependent Claims (61, 62, 63, 64, 65, 66, 67, 68, 69, 70, 71)
