The present disclosure relates to various methods for measuring the amount of an analyte present in a biological fluid using an electrochemical testing process. Various embodiments are disclosed, including the use of AC test signals and the performance of tests having a Total Test Time within about 3.0 seconds or less, and/or having a clinically low Total System Error.
1. A method for determining a concentration of an analyte of interest in a biological sample, comprising: a) applying a first signal having a first AC component to the sample;b) measuring a first response to the first signal;c) applying a second signal having a second AC component to the sample;d) m
1. A method for determining a concentration of an analyte of interest in a biological sample, comprising: a) applying a first signal having a first AC component to the sample;b) measuring a first response to the first signal;c) applying a second signal having a second AC component to the sample;d) measuring a second response to the second signal;e) applying a third signal having a third AC component to the sample;f) measuring a third response to the third signal;g) applying a fourth DC signal to the sample;h) measuring a fourth response to the fourth DC signal; ande) determining the analyte concentration of the sample using at least the first, second and third responses to correct the fourth response for the effects of at least one interferent within the sample, wherein the determination has a Total Test Time of within about 2.0 seconds or less, and wherein the first, second third, and fourth signals are applied to the sample during separate time periods;wherein the first signal is applied for no more than about 100 ms before the first response is measured;wherein the second signal is applied for no more than about 100 ms before the second response is measured;wherein the third signal is applied for no more than about 100 ms before the third response is measured; andwherein the fourth signal is applied for no more than about 200 ms before the fourth response is measured. 2. The method of claim 1, wherein the determination has a Total Test Time of between about 0.5 seconds and about 1.525 seconds. 3. The method of claim 1, wherein the method has a Total System Error of less than about 11%. 4. The method of claim 1, wherein the biological sample is blood and the analyte of interest is glucose. 5. The method of claim 1, wherein the first, second and third signals each comprise an AC signal, each AC signal having a different frequency, and wherein the fourth signal comprises a DC signal. 6. The method of claim 1, wherein the interferent comprises one or both of hematocrit and temperature. 7. The method of claim 1, further comprising: applying a fifth signal having a fourth AC component to the sample during a separate time period from the first, second, third and fourth signals; andmeasuring a fifth response to the fifth signal;wherein said determination of the analyte concentration of the sample uses at least the first, second, third and fifth responses to correct the fourth response for the effects of at least one interferent within the sample; andwherein the fifth signal is applied for no more than about 100 ms before the fifth response is measured. 8. The method of claim 7, wherein the first, second, third and fifth signals each comprise an AC signal, each AC signal having a different frequency, and wherein the fourth signal comprises a DC signal. 9. The method of claim 7, wherein the first signal is a 10 kHz AC signal, the second signal is a 20 kHz AC signal, the third signal is a 1 kHz AC signal, and the fifth signal is a 2 kHz AC signal. 10. The method of claim 7, wherein the fourth signal is applied for no more than about 200 ms before the fourth response is measured. 11. The method of claim 7, wherein the method has a Total System Error of less than about 11%. 12. The method of claim 11, wherein the method has a Total System Error of between about 7.5% and about 11%.
