Abstract From the Canadian patent

A method and apparatus are described that permit an analyte concentration to be estimated from a measurement in the presence of compounds that interfere with the measurement. The method reduces the error in the analyte concentration in the presence of interferents. The method includes the use of a set of measurements obtained for a large population having a range of know analyte and interfering compound concentrations. From a sample measurement which may or may not be one of the population likely present interferents are , identified and a calibration vector is calculated.
