Abstract

A method of using a meter to determine an analyte concentration of a fluid sample. The method includes providing a meter with stored default calibration information and stored generic calibration information. The method further includes providing a package including at least one test sensor to receive a fluid sample to be analyzed. The method additionally includes placing the package into the meter and determining whether the received package includes an auto-calibration circuit or label. If the test sensor does not include the auto-calibration circuit or label, the method utilizes the stored default calibration information in the meter to determine the analyte concentration of the sample received by the test sensor. If the test sensor includes the auto-calibration circuit or label, the method utilizes the auto-calibration circuit or label and the stored generic calibration information to determine the analyte concentration of the sample received by the test sensor. The method further includes placing the fluid sample on the test sensor and determining the analyte concentration of the sample.
