Gluco Rx HCT Glucose Test Strips Gluco Rx HCT Glucose Test Strips are designed for use with the Gluco Rx HCT & Ketone Blood Glucose Monitoring System to detect glucose in the blood. They have a measurement range of 0.5 to 35 mmol/L & provide results in just 5 seconds using a small 1.0L blood sample. Gluco Rx HCT Glucose Test Strips use advanced GDH-FAD enzyme technology with 2+2 (AC & DC) Bio Signal. The AC signal works to provide the haematocrit result, & DC calculates glucose. The meter then corrects the glucose level according to the haematocrit value for enhanced accuracy.
