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.
Claims9
A method for measuring hematocrit (HCT) and/or prothrombin time (PT) of a sample, comprising:
- providing a test card assembly to a test card receiving unit;
- providing a sample to be inspected to the test card assembly;
- providing an alternating current with predetermined frequency and voltage to the test card assembly by an AC generation unit;
- receiving a response signal from the test card assembly;
- performing a reactance analysis of the sample;
- determining the HCT and/or the PT with a microprocessor;
- and
- providing an inspected result to a display unit.
