Abstract
A method of measuring hematocrit (HCT) and a measurement device using in the method and depends on an electrode test specimen to create a capacitor charging effect and consequential change in discharge current for measurement of hematocrit. The method of measuring hematocrit comprises steps as follows: (a) Instill blood into a pair of test electrodes which is installed in the present invention and apply a voltage to the pair of test electrodes; (b) Remove the voltage applied to the pair of test electrodes and measure a discharge current value; (c) Refer to a predetermined decision rule and the discharge current to obtain a hematocrit value for blood. As such, the present invention which relies on an electrode test specimen in measurement of hematocrit corresponding to a discharge current value during electric discharge contributes to precision and reliability in contrast to conventional hematocrit tests.
