A first user equipment includes a display, at least two communication mechanisms that respectively supports a first and a second communication mode, and a processor communicatively coupled to the display and the communication mechanisms. The method includes the steps of lysing red blood cells of a blood sample with a lytic reagent, measuring nucleated blood cells by DC impedance measurement in a non-focused flow aperture, differentiating nucleated red blood cells from other cell types, and reporting nucleated red blood cells in the blood sample. The first and second bar-shaped antenna elements is positioned such that one end of each of the first and second bar-shaped antenna elements is close to the third bar-shaped antenna element, and the other end is far from the third bar-shaped antenna element. Furthermore, the replay display and the real time image are simultaneously displayed.
