Abstract
This invention is a method for determining a hematocrit value. The steps include applying a first pulse of potential excitation at a first frequency to a test strip containing a fluid sample. The method also includes applying a second pulse at a second frequency that is higher than the first frequency. Based on first and second impedance measurements associated with each pulse, a hematocrit value may be determined. Also, a concentration of an analyte contained within the fluid sample may be determined based on the hematocrit value.
