Abstract

A test system comprises a sensor container and a testing device. The sensor container has a base and a lid. The container encloses test sensors therein. The container includes a calibration label attached thereto. The label includes electrical contacts located thereon. The electrical contacts encode calibration information onto the calibration label. The testing device has an auto-calibration feature externally located thereon. The testing device is adapted to determine the analyte concentration in a fluid sample. The auto-calibration feature includes calibration elements that communicate with the electrical contacts on the calibration label. The testing device is adapted to determine the calibration information encoded on the calibration label in response to the calibration elements engaging the electrical contacts. The encoded calibration information is determined without inserting the sensor container or the calibration label into the testing device.
