Abstract
A test strip for measuring an analyte level in a fluid sample includes a sample chamber configured to receive the fluid sample; a plurality of electrodes configured to produce at least one current measurement related to the analyte level in the fluid sample; and at least one information-providing connector having an intrinsic electrical property representative of at least one test strip calibration parameter specific to the test strip. A system for measuring an analyte level in a fluid sample may include such a test strip along with a data acquisition system controlled by a processor and configured to measure an intrinsic electrical property of the information-providing connector and to obtain at least one test strip calibration parameter corresponding to the test strip from at least one predetermined location in a memory based on the intrinsic electrical property.
