Patent ID: 7996988

Claim:
A method of making a plurality of calibration-adjusted sensors for use in determining a concentration of a ketone body in a sample, the method comprising: (a) providing a plurality of pre-sensors, each pre-sensor comprising a working electrode, a counter electrode, and a sample chamber, wherein the sample chamber has at least part of the working electrode and the counter electrode arranged therein, wherein the plurality of pre-sensors include at least a first pre-sensor and a second pre-sensor; (b) physically modifying the first pre-sensor to form a first sensor, the first sensor having a first physical characteristic defining a first slope and a first y-intercept; (c) determining the first slope and the first y-intercept of the first sensor; (d) comparing the first slope of the first sensor to a first desired slope and comparing the first and y-intercept of the first sensor to a first desired y-intercept; and (e) physically modifying the second pre-sensor to form a second sensor having a second physical characteristic defining a second slope and a second y-intercept of the second sensor such that the second slope of the second sensor is substantially equal to the first desired slope and such that the second y-intercept of the second sensor is substantially equal to the first desired y-intercept.
