Abstract: A device for the quantification of cellular and non-cellular components in a blood sample including detection electrodes including a first electrode connected with a first input to receive a first signal in input and a second electrode, reference electrodes including a first electrode connected with a second input configured to receive a second signal in input of opposite polarity to the first input signal and a second electrode connected to the second electrode of said detection electrodes, in a common point wherefrom an output signal is picked up, a ferromagnetic concentrator that cooperates with an external magnetic field external to effectuate concentration of said components on said detection electrodes, a substrate configured to house said detection electrodes, reference electrodes, and concentrator; a support configured to collect a blood sample, and a spacer element to confine in the substrate plane the blood sample and to distance said substrate from said support.

Abstract: Apparatus (100) for the quantification of biological components (3, 3?, 3?) in a fluid comprising: a measurement cell (1) comprising detection electrodes (4, 4?, 5, 5?, 6, 6?, 34, 34?, 84, 84?, 94, 94?, 184, 184?, 194, 194?) and reference electrodes (7, 7,? 8, 8?, 9, 9?, 37, 37?, 64, 64?, 74, 74?, 164, 164?, 174?); an electronic unit (201) for the generation of input signals, impedimetric measurement, amplification of output signals and communication with a user interface; means for the generation of a magnetic field (101, 102, 103) with an appropriate gradient that can be modulated in time, said means of magnetisation being configured to generate a magnetic field capable of causing, in combination with concentrators (10, 10?, 10?, 14, 14?, 14?, 15) housed in the measurement cell, the separation of the components (3, 3?, 3?) to be quantified from the rest of the solution and their concentration on the detection electrodes (4, 4?, 5, 5?, 6, 6?, 34, 34?, 84, 84?, 94, 94?, 184, 184?, 194, 194?).
