Abstract
Systems and methods for hematocrit measurement are provided. In some embodiments, a method for measuring glucose in a blood sample comprises measuring hematocrit in a blood sample using a Thevenin equivalent circuit to calculate a hematocrit complex impedance value, mapping the calculated hematocrit impedance to a hematocrit concentration in the blood sample, and calculating a concentration of glucose in the blood sampled using the mapped hematocrit concentration.

A method for measuring glucose in a blood sample, comprising:
- measuring hematocrit in a blood sample using a Thevenin equivalent circuit to calculate a hematocrit complex impedance value;
- mapping the calculated hematocrit impedance to a hematocrit concentration in the blood sample;
- and
- calculating a concentration of glucose in the blood sampled using the mapped hematocrit concentration.
A system for diagnostic testing comprising:
- a test strip;
- and
- an electronic meter for performing a diagnostic test on a sample applied to the test strip inserted therein, the electronic meter comprising:
- a housing having a test port for receiving the test strip, and
- a processor programmed to perform the steps of:
- measuring hematocrit in the sample placed onto a test strip using a Thevenin equivalent circuit to calculate a hematocrit complex impedance value;
- and
- mapping the calculated hematocrit impedance to a hematocrit concentration in the blood sample;
- and
- calculating a concentration of glucose in the sample using the mapped hematocrit concentration.
A method for measuring glucose in a blood sample, comprising:
- detecting a blood sample;
- measuring hematocrit in the blood sample placed onto a test strip using a Thevenin equivalent circuit to calculate a hematocrit complex impedance value;
- and
- mapping the calculated hematocrit impedance to a hematocrit concentration in the blood sample;
- applying an excitation signal to the blood sample such that the response to the excitation signal is analyzed to determine a glucose concentration in the blood sample;
- adjusting the glucose concentration in the blood sampled using the mapped hematocrit concentration;
- and
- displaying the adjusted glucose concentration.
