Patent ID: 8486649

Claim:
A method of calculating an analyte concentration of a sample, comprising: introducing a sample to an electrochemical cell that includes a first electrode and a second electrode; applying a first test voltage V 1 for a first time interval T 1 between the first electrode and the second electrode sufficient to at least partially oxidize a reduced mediator at the second electrode; applying a second test voltage V 2 for a second time interval T 2 between the first electrode and the second electrode sufficient to at least partially oxidize the reduced mediator at the first electrode; calculating an initial analyte concentration of the sample based on at least one test current value determined during the first time interval T 1 and the second time interval T 2 ; calculating an error source of the sample; and calculating a corrected analyte concentration based on the initial analyte concentration and the error source; wherein the analyte includes glucose and the error source includes a hematocrit level H of the sample, the calculating steps being calculating an initial glucose concentration G 1 of the sample based on at least one test current value determined during the first time interval T 1 and the second time interval T 2 , calculating the hematocrit level H of the sample, and calculating a corrected glucose concentration G 2 based on the initial glucose concentration G 1 and the hematocrit level H.
