Abstract
Methods are disclosed for measuring an analyte concentration in a fluidic sample. Such methods allow one to correct and/or compensate for confounding variables such as hematocrit, salt concentration and/or temperature before providing an analyte concentration. The measurement methods use response information from a test sequence having at least one DC block, where DC block includes at least one excitation pulse and at least one recovery pulse, and where a closed circuit condition of an electrode system is maintained during the at least one recovery pulse. Information encoded in the excitation and recovery pulses are used to build within- and across-pulse descriptors to correct/compensate for hematocrit, salt concentration and/or temperature effects on the analyte concentration. Methods of transforming current response data also are disclosed. Further disclosed are devices, apparatuses and systems incorporating the various measurement methods.
