Abstract

Methods and devices for determining the concentration of a constituent in a physiological sample are provided. The physiological sample is introduced into an electrochemical cell having a working and counter electrode. At least one electrochemical signal is measured based on a reaction taking place at the cell. The preliminary concentration of the constituent is then calculated from the electrochemical signal. This preliminary concentration is then multiplied by a hematocrit correction factor to obtain the constituent concentration in the sample, where the hematocrit correction factor is a function of the at least one electrochemical signal. The subject methods and devices are suited for use in the determination of a wide variety of analytes in a wide variety of samples, and are particularly suited for the determination of analytes in whole blood or derivatives thereof, where an analyte of particular interest is glucose.
