Abstract
Embodiments of the present invention improve the accuracy of measurements and/or in vivo calibrations of a biosensor by (1) using more than one sensor signal value and/or more than one directly sampled and measured value, such as a capillary blood glucose value, and/or by (2) delaying the acquisition of a sensor output value that is compared with a directly sampled and measured value, such as a capillary blood glucose value, during a calibration. In an embodiment of the present invention, the median of a series of measured values, or a median or mean of the medians, may be utilized to provide more consistent and accurate measurement data and/or to compensate for error or artifact.
