SYSTEMS AND METHODS FOR HEMATOCRIT IMPEDANCE MEASUREMENT USING DIFFERENCE IDENTITY PHASE

摘要

The present disclosure provides a system for measuring a property of a sample comprising: a test strip for collecting the sample; a diagnostic measuring device configured to receive the test strip and measure a concentration of an analyte in the sample received on the test strip; and the diagnostic measuring device further comprising a processor programmed to execute an analyte correction for correcting a measurement of the sample due to one or more interferents, comprising: calculating an interferent impedance measurement including a magnitude measurement and a phase measurement using a difference identity to generate a sinusoidal signal with an amplitude proportional to the phase difference; and adjusting the measurement of the analyte in the sample using that the calculated interferent impedance measurement.
