Abstract: Examples herein provide a device. The device includes a testing cassette including: a microfluidic channel connecting an input port at a first end to at least one sensor area at a second end, the channel is to allow a blood sample to flow from the input port to the at least one sensor area; at least two electrodes; and a micro-fabricated integrated sensor, wherein when an electrical potential difference is applied over the blood sample, the sensor is to measure, over a duration of time, an electrical signal passing through the blood sample as the blood sample flows from the input port to the at least one sensor area and begin to coagulate, thereby obtaining a measurement function as a function of time. The device includes a processor to correlate the measurement function to a characteristic of the blood sample.
