A method of measuring an analyte in a biological fluid comprises applying an excitation signal having a DC component and an AC component. The AC and DC responses are measured; a corrected DC response is determined using the AC response; and a concentration of the analyte is determined based upon the
A method of measuring an analyte in a biological fluid comprises applying an excitation signal having a DC component and an AC component. The AC and DC responses are measured; a corrected DC response is determined using the AC response; and a concentration of the analyte is determined based upon the corrected DC response.

What is claimed is: 1. An instrument for determining concentration of glucose in a blood sample, comprising: a display; first and second terminals for contacting complimentary first and second terminals of an electrochemical cell adapted to receive a blood sample; an assessment controller configure
What is claimed is: 1. An instrument for determining concentration of glucose in a blood sample, comprising: a display; first and second terminals for contacting complimentary first and second terminals of an electrochemical cell adapted to receive a blood sample; an assessment controller configured and arranged to: detect deposit of the sample in the cell; determine sufficiency of volume of the deposited sample; determine a correction value based on an electrical response from the cell; obtain an indicated glucose concentration by assessing a reaction of glucose in the blood sample with a chemistry provided in the cell; apply the correction value to the indicated glucose concentration to arrive at an actual glucose concentration, the actual glucose concentration comprising a compensated indication of the glucose concentration; and display the actual glucose concentration on the display no more than 10 seconds from the detection of deposit of the sample. 2. The instrument of claim 1, wherein the determine sufficiency of volume step further comprises the steps of: applying a first signal to at least one of the first and second terminals of the electrochemical cell; measuring a first response to the first signal. 3. The instrument of claim 2, wherein the first test signal comprises a signal having an AC component. 4. The instrument of claim 3, wherein the first test signal comprises an AC signal. 5. The instrument of claim 1, wherein the determine a correction value step further comprises the steps of: applying a first signal to at least one of the first and second terminals of the electrochemical cell; measuring a first response to the first signal. 6. The instrument of claim 5, wherein the first test signal comprises a signal having an AC component. 7. The instrument of claim 6, wherein the first test signal comprises an AC signal. 8. The instrument of claim 1, wherein the obtain an indicated glucose concentration step further comprises the steps of: applying a first signal to at least one of the first and second terminals of the electrochemical cell; measuring a first response to the first signal. 9. The instrument of claim 8, wherein the first test signal comprises a signal having an AC component. 10. The instrument of claim 9, wherein the first test signal comprises an AC signal. 11. The instrument of claim 1, wherein the actual glucose concentration is correlated with the glucose in the blood sample by at least r2=0.9400. 12. The instrument of claim 11, wherein the actual glucose concentration is correlated with the glucose in the blood sample by at least r2=0.9800. 13. The instrument of claim 12, wherein the actual glucose concentration is correlated with the glucose in the blood sample by at least r2=0.9900.
