Patent ID: 7212925

Claim:
A test device for determining the concentration of an analyte in a sample, the test device having a memory in which a plurality of calibration adjustments corresponding to a plurality of calibration numbers is stored, the test device being adapted to receive a test sensor for collecting the sample, the test sensor containing a reagent adapted to produce a reaction indicative of the analyte concentration in the sample, the test sensor having an associated calibration number of a plurality of digits, the device comprising: a measuring unit adapted to measure the reaction of the reagent and the analyte and to generate a signal indicative of the measured reaction; a single calibration input element adapted to permit a user to input the calibration number, one digit at a time, associated with the test sensor; a processor electronically coupled to the single calibration input element and the measuring unit, the processor being adapted to determine the analyte concentration in the sample in response to receiving the inputted calibration number and receiving the signal indicative of the measured reaction from the measuring unit; and a user display electronically coupled to the processor for displaying digits to be selected by a user inputting the calibration number and for displaying the determined analyte concentration in the sample.
