Abstract
A biosensor system determines an analyte concentration using one or more calibrated correlation equations for an optical and/or electrochemical analysis of a biological fluid. The biosensor system may be implemented using a measurement device and a sensor strip. The measurement device senses circuit patterns on an encoding pattern of the sensor strip. The measurement device determines calibration information in response to the circuit patterns, and uses the calibration information to calibrate one or more of the correlation equations. The measurement device uses the calibrated correlation equations to determine the analyte concentration.
