Abstract

Devices and methods for measuring prothrombin time (PT) and hematocrit (HCT) by analyzing the change in reactance in a sample are presented. A diagnostic device for measuring HCT and PT of a fluid includes a relative electrode-type sensor device and a blood test card assembly including one or more pairs of electrodes, wherein alternating current (AC) provided by the sensor device is used to measure and calculate HCT and PT of blood test using the reactance analysis.
