The ink-jet recording apparatus includes a suction force generation unit for collecting ink configured to enable the suction collection section to generate a suction force, a collection flow path connecting the suction collection section to the suction force generation unit for collection, and a flow path control unit configured to vary an sectional area of the collection flow path. Detection of the coagulation response can be achieved through optical probing or by measurement of physical effects of the blood sample binding to the planar surfaces, and restricting movement thereof. Finally, a reading voltage is applied to the second bit line to acquire a reading current which is the sum of total current through the symmetrical dual-channels for increasing the reading speed of the non-volatile memory.
