The invention relates to a technique for detection by using an improved polybrene microplate before blood transfusion. In the technique, the designed microplate (figure 1) is used instead of used consumable items and supporting facility and no test tube nor centrifuge is used, and on the other hand, the concentration and dosage of a polybrene reagent are changed. The polybrene is a tetraamine polymer which can neutralize negative electric charges on red blood cells, reduce the Zeta electric potential and shorten the distance between cells. Under the condition of a low concentration, a reversible nonspecific hemagglutination phenomenon can appear when the distance between the red blood cells is shortened; and when the concentration of the polybrene is increased, the red blood cells directlyform nonspecific hemagglutination. When the negative electric charges on the surfaces of the red blood cells are restored, the hemagglutination phenomenon disappears because of the repulsion of the negative electric charges among the red blood cells, but the affinity or the agglutination, really caused by the antigen antibodies of the red blood cells, of the antigen antibodies does not disappear.
