Patent ID: 8105841

Claim:
An assembly for determining an analyte concentration in a fluid sample, comprising: a test sensor comprising a fluid-receiving area for receiving a fluid sample, the fluid-receiving area containing a reagent that produces a measurable reaction with an analyte in the sample, the test sensor having a test-sensor temperature and the reagent having a reagent temperature; a meter comprising: an opening configured to receive the test sensor; a measurement system configured to determine a measurement of the reaction between the reagent and the analyte; and a temperature-measuring system configured to determine a measurement of the test-sensor temperature when the test sensor is received into the opening, wherein the meter determines a concentration of the analyte in the sample using the measurement of the reaction and the measurement of the test-sensor temperature, wherein the temperature-measuring system comprises a thermopile sensor configured to determine a measurement of the test-sensor temperature by measuring infrared radiation from an area of the test sensor disposed inside the meter.
