A small blood sample is applied to our specialized test strip to quantify blood glucose and insulin and calculate insulin resistance. Our particular biosensor uses an electroenzymatic approach to determine the amount of glucose and insulin in the blood sample.
The test strip consists of three different electrode layers and immobilized electrochemicals that bind specifically to glucose and insulin, respectively. When blood is placed on the test strip, the analyte (glucose or insulin) binds to their specific aptamer. The transducer converts the analyte-aptamer reaction into an electrical current that is directly proportional to the concentration of the measured biomarker (glucose or insulin). The current is then converted to a voltage, the voltage is amplified and the electronics process the signal. The concentration of glucose and insulin and the calculated insulin resistance is then depicted on the display.
